While it’s not bad, and it’s actually fairly good, you could have eased up on the dithering. In some sense it feels like the mountains have the same texture as the sky and I’m not sure if the black outline is helping that. What I do love about the piece is that the concept for this piece is actually pretty solid and that’s where I feel like it could have been pushed further.
Also you could have made the watermark way smaller or figured a way out to put a signature in the piece.
Regardless, I’d like to offer to scout you. You have a lot of potential and I would like to see more of what you got and see how far you can push yourself.
