a stupid painting

I've never really done landscapes and Im not good at photoshop so this is probably pretty bad. That mountain goat looks abysmal. Next year I will probably look at this whole thing and throw up. But that's the thing, like I saw a painting of mountains I did like, 2 years ago? -> zemie.deviantart.com/art/Mount… and I was like :barf: so I tried to do something better and I think it turned out pretty rad. For now. 
I still have no idea how to make colors look good. That is a goal of mine
