Pretty good!
I really like the background you made up, all snowy, but in my oppinion the blimp is just a little too noticeable, not sure if you were going for that though. you keep mentioning what programs you used to make your art, not really interested in that, I want to know what inspired you to make your work, and why you did it. This work of art looks like it would be a fantastic background for a movie.
