Nice artwork here
Now this one was pretty neat you have some good ideas here its a cup but its so much more then that with a whole world there, so thats was a plus, i like how you brought the two together and made it pretty unique, the design on city and backrounds seemed to comeout well so nice job all around, but as for improvment i dont know i think you have done an outstanding job regardless.
~~THINGS TO IMPROVE ON~~
I suppose if anymore improvments are to be made you could go by adding some people maybe climbing mountains or even swimming in the coffee/coco.
