create a highly photorealistic architectural visualization based strictly on the provided image important do not modify the architecture layout dimensions proportions geometry circulation pathways furniture placement hardscape design terrain shape camera angle or overall design intent preserve the original composition exactly as shown the task is to improve realism only not to redesign the project the existing mature trees are an important part of the design and must remain in their current locations improve their realism through natural canopy variation realistic bark textures subtle leaf color differences and accurate light penetration through the foliage in the center of the courtyard exactly in the location visible in the reference image introduce a simple rectangular wooden terrace integrated into the design the terrace should be elevated approximately 15 cm above the surrounding ground level and constructed from high quality light natural wood decking boards the terrace must appear as a permanent architectural element of the original project with clean detailing realistic timber texture subtle weathering and physically accurate shadows beneath the structure no railings fences pergolas or additional structures should be added unless already present in the original image apart from this terrace all existing spatial relationships and design elements must remain unchanged surface materials preserve all existing paving and landscape elements areas shown as lawn should be rendered as healthy natural grass with realistic variation in height density and color where concrete stepping slabs occur within the lawn maintain approximately 10 cm grass joints between slabs improve the realism of all hardscape materials with subtle imperfections weathering texture variation and physically accurate reflections small architecture and furniture all benches pergolas screens and wooden landscape elements including the new terrace should be rendered in high quality light natural wood add realistic wood grain subtle imperfections and physically accurate material properties do not change the form dimensions or placement of any architectural element vegetation add vegetation carefully and sparingly the landscape should remain clean elegant calm and appropriate for a healthcare environment do not overcrowd the project with planting the primary goal is to enhance realism while preserving open space and the original design concept emphasize ornamental grasses especially naturalistic compositions based on stipa tenuissima ponytails calamagrostis acutiflora karl foerster deschampsia cespitosa festuca amethystina carex montana miscanthus sinensis goliath if additional plants are needed use only the following species and do not introduce any others aconitum carmichaelii arendsii liatris spicata aster samoa salvia nemorosa veronicastrum virginicum fascination verbena bonariensis digitalis mertonensis astilbe chinensis

ponytails miscanthus sinensis goliath deschampsia cespitosa calamagrostis acutiflora karl foerster hedera helix hakonechloa macra dryopteris filix mas arrange plants in realistic landscape architecture compositions with natural groupings and restrained quantities avoid excessive flowering displays the overall appearance should remain calm therapeutic and suitable for a hospital setting human figures this is a hospital courtyard a small number of people may be added to increase realism but only adults replace any artificial looking figures with highly realistic adults such as patients visitors medical staff elderly people people should be shown naturally walking sitting resting reading talking quietly or enjoying the outdoor space do not include children playground elements sports activities fitness exercises running large crowds exaggerated poses keep human presence subtle and believable rendering quality ultra photorealistic architectural visualization competition quality landscape rendering realistic natural daylight physically accurate shadows high quality global illumination realistic ambient occlusion accurate material behavior natural depth of field realistic camera lens characteristics subtle atmospheric effects natural color grading no cgi appearance no oversaturated colors no artificial vegetation no excessive contrast target result a premium landscape architecture visualization that looks like a professional architectural photograph of a completed hospital courtyard while fully preserving the original design architecture layout and spatial character the newly introduced central wooden terrace should appear naturally integrated into the project and constructed from high quality light timber elevated approximately 15 cm above the surrounding terrain
