Yup I accept it doesn´t have unity, but that´s because this was planned to be three different pieces, after that I made a bigger canvas to join then, that´s why you can see three styles ^^U...
Appart from that I really appreciate the comment, I will work more on this one and reupload it with changes (I think I will create a thread in the Wip section ^^)
Once again, thanks! =D...
I'm not seeing a lot of unity in your design... you have different styles within the piece it seems. I can't really tell whats going on in the top right of the clouds, I can tell there's a sun though.
The brown mountains kind of look like a... melty baby ruth chocolate bar.
some of the clouds (i'm guessing) look good right over the taller building, and the ground looks like it has veins...
Try to unify style and to kill «dead pixels» — there is a huge amount of PA unused (but i can think that there is a lot of a ground to bury people at right?). And add more details — the pic will be better.
