I have made an mistake...

/sorry for my english ;</

 

I third that idea. But I think overall this is okay. But why is this in the c ategory of  "Robots"

i agree with haash, and maybe you should also try to make it look more like an atmosphere... like adding more greyish and faded mountains behind the mountains you already have... But anyways looks very good!

Very good work for a first try, though the perspective bothers me a little, specially in the little house...
