Sci-fi ! Cool. All ya need to do in these is to start puttin in more details with a harder brush...like ya did with joy's hair.. cool

Now this, this is my kind of stuff. Ask anyone. Love sci fi. The sky and clouds are wonderful. And damn cool ship. *watch out birdie, watch out*

Just take the outlines off the buildings and make the foreground darker so everything pops out more. Do more of these.

Better, the buildings definately look more in the background. Now you have to learn not to be shy using darks and lights (something I still have a bit of a problem with :})
