As mentioned the statue not being iso and the praying guys (praying in Western style and not Buddhist) is something that you may want to revise/edit when you get more of that practice you speak of, lol.
When making any art, pixel or not. The main attraction will either make or brake the whole thing. This appears to be the central item in this mutli scene block and because its weaker than less important parts in the scene it stands out more. Of course the gradients and overall lighting of the statue is rather wonky.
The whole scene is original and lots of effort and work on your part is evident so its a win and my crits are only meant to help you in future projects only
