Painting of a landscape

For art we had to paint a landscape. I got a 7 for it. I think I maybe could get a little bit higher mark for it, but I also understand why I haven't: The switch of the colours in the sky is not so nice. That's because I painted the sky in two different lessons so I couldn't get the same colours again.

I also don't really like the colour of the mountains in the front. But I do like the foggy mountains in the back.
