Well, for the first it was a great effort. In the future I suggest using some kind of vector-based program or paths in gimp for the shapes that need to be crisp. Also, I don't like smudging, it's cheep. But u are good in mapping department so it's a plus!
And colors fits.
It's good that u always can work on your set, re-done it, part by part, and improve as time past.
5/10.
