I painted a fan art for a streamer.

This is far from my first painting and I do have some previous experience with Photoshop/digital art but I don't regularly practice it.

That said, can you please critique and provide feedback for everything you see in this painting? Things I have missed and need to improve on?

Also would you say I have potential to create 2D game assets for personal use; would you play a game in this style?

This looks pretty nice visually, and you make good use of lighting and texture, but I think your perspective could use a little work.

You could definitely make some nice 2d assets for a game with this style.
