Hah, I think that I can understand the difficulities in coloring the desert. Its never and easy job. The lineart is pretty good from what I see. The coloring can still be improved though. You can add more shading, correction, a lot more shadings to the clothes and the desert. I like that dense light though. It really does make it look bright and sunny. Good job overall. Keep working on those minor parts.
I was thinking about making a v2, but since I don't have much time, because cleaning manga takes a lot of time.. and school and other stuff.. so I dunno when I have time to make it. but I'll defently make a v2^^
