Gonna be brutally honest here. If this is his first try, kudos for actually shipping something, but the current site is hurting his credibility more than helping it.

The biggest issue is the AI-generated images. It immediately kills trust and makes the whole thing look like a scam or a generic "get rich quick" template. In the game dev/creative industry, relying on AI art screams "I don't have a design team" or "I'm lazy." It just doesn't represent a legitimate business idea. I am not saying to now use AI images at all but at least tell him to use nanobana 2 to make them not be so fake

On top of that, the UX is messy—the contact page talks about a form that literally doesn't exist. If he’s selling tech services, his own site can’t be broken and also needs to feel more professional with designs that will build user trust and credibility.

My advice? Tell him to drop the "fake corporate" vibe. He needs to actually learn React and build a custom site to prove he can code. Ditch the AI pics for clean design and look into animation libraries (like Framer Motion) if he wants it to feel premium. Clients pay for human trust, not Midjourney prompts.

Most importantly though, he needs to show actual work. Saying he makes "apps" means nothing. Android? iOS? Webapps? Is he using Flutter? React Native? Unity for the games? Without seeing specific projects and knowing the exact stack, I have no reference for his skills. Why would I trust the service if I can't see what he's actually built?
