Another Spray Can work

This is really just a practice piece, and is a little sloppy, but, gosh, this stuff really is fun. ...
I'd like to do ocean themes. Dolphins and whatnot. But the "space theme" is the easiest for the novice spray painter. ...
A lot of guys do this stuff and sell it on the street, and appear to do brisk business. A couple even do small ones for the party favor business, just like caricaturists. Hmm...
But a lot of these guys aren't really artists, I don't think. They just learned some simple techniques. I think my "artistic eye" will help if I pursue this medium further.
