I don't like that line where it begins to show your reflection and the fade to the bottom

For your first, this is really good man. The sharpening is perfect

IMO, it could use a little more lighting, but just a tad, use it brighten up the dark blue in the top left corner. Also, your text placement needs some work, it coincides with your smudging in the clouds. If you leave that text there, make sure you make it smudge into the clouds. Really, this is pretty good
