SharkoLove the design, it reminds me of some of Eric Pollard's designs without being derivative of his aesthetic.
From top to bottom we are looking at the sun and mountains, then the mountains reflected in a lake, then trees on the near bank of the lake, then the shadows of those trees, right?
I would suggest also having the sun reflected in the lake.
I would also suggest changing the color palate. Although I like the white background, the mountains being blue makes the reflection a little hard to read. It's easy at first glance to read the white water as snowy mountain peaks with the upside down blue reflected mountains as sky. I would suggest flipping the color palate so that the sky and water are blue and the mountains white or grey. I think this would be more readable. On the other hand, it would be a more literal/concrete representation of your subject which might not be the aesthetic you're going for. If that's the case, making the mountains red or purple would also help prevent the reflected mountains from looking like sky.
Was not expecting that much detail of a response, thanks so much. The colors were a little wonky when I originally exported them, soI just reuploaded it. I completely forgot about putting down the sun on the reflection. I originally didn't mean for it to look like a reflection, but it ended up just looking like that so I think I'm going to try running with it. I'll also try working with the mountain colors, maybe purple because that should look good with the orange sun, whenever I get time.
