Hi!
Here’s my latest artwork, I made 2 of 1 scene 
Here’s more details: https://www.artstation.com/artwork/r24om
Looks nice, especially the first image. But I don’t know if whole scene is under water or not, because of the overall tint and sun rays. At the other side, there is grass, so… I don’t know 
But the tree bark with moss is really cool.
Second image is also nice, but lens distortion is too big in my opinion.
Yeah, that could be, I tried to made it a bit fantasy themed, so I liked that tint. And about the lens distortion I was aware if was too much, but I really liked the effect that it generating while it was really focusing the point of attention to the center of the scene and also It was giving me a bit of mystics so I liked that 
Thank you!
