Realistic Kids Go-Kart Composite

I have separate, high-resolution photos of my children and their actual go-kart and I’d like them blended into one seamless, realistic image set on a race-track backdrop. The final piece should look as if it were captured in a single shot—consistent lighting, shadows, colour grading and perspective all aligned so nothing feels “pasted on.” You will receive: • Two individual portraits (head-to-toe) of the kids shot outdoors in decent light • A clear photo of the go-kart from a similar angle What I need back: • A print-ready composite (minimum 4000 px on the long edge, 300 dpi) in JPEG or PNG • A layered PSD or TIFF so I can make minor tweaks later if needed Please use non-destructive editing in Photoshop or a comparable tool, keep the skin tones true to life, and ensure the tyres, reflections and track surface interact naturally. If any extra stock elements are required for the race-track background, let me know before purchase so I can approve. Let me see a quick low-res proof for feedback on positioning and colour balance, then proceed to the final polish and export. Budget: INR 600–1500
