After using a wood texture (referrence), I started to get how to do the texture on the wood. But I believe the wood lacks contrast? Right?
Let me know, thanks 
The important part that the wood floor should not compete for attention and be only a background element. If you go deeper into game art, you'll eventually figure that game assets never exist in a vaccuum. It's hard to judge a game asset by itself and you're gonna want to see how everything meshes together in a unified game screen.
