Guys, what are signs you aren't interested in a girl anymore?

I'm not sure if this guy is shy or just not interested anymore. Before, he was trying to be around me and he often smiled at me. My friend thought he liked me too because he was obvious. But the other day he didn't say hi even though I'm sure he saw me. He kind of seems to avoid me now.

However we recently talked to each other again about a project, we locked eyes during the whole conversation, he wasn't smiling but when I smiled at him he smiled back and I could tell it was a genuine smile because his eyes were shining and he had crinkles around them. But that's it. When he left his face was neutral again. Does he seem like a guy who lost interest or am I overthinking? Just wanted to be sure, thank you :)
