Add Railing to Patio Rendering

I have a finished 3-D patio rendering and a separate reference photo that shows the exact railing style I want. Your job is to insert that railing digitally so the final image looks as if it was designed that way from the start. Key points you need to know • Style: replicate the railing in my reference image—no reinterpretations, no simplifications. Every post, panel, and fastening detail should read the same once the image is zoomed in. • Placement: I’m including an overhead plan that marks the edges where the railing belongs. Follow that guide precisely; anywhere unmarked should stay untouched. • Consistency: lighting, reflections, and shadows on the new railing have to match the existing render so the addition is seamless. Deliverables 1. Updated high-resolution JPEG/PNG ready for client presentation. 2. Layered file (PSD, TIFF, or the native file from your 3-D software) so I can adjust colours later if needed. I work in Photoshop and SketchUp myself, so feel free to use those or any equivalent tool—just be sure the output is clean and layered. Let me see a quick low-res proof first; once approved, send the finals.
