Thanks, Rad! I went ahead and re-worked my drawing with your crits in mind. I keep amazing myself with my drawings because I remember back to a year ago when I pretty much had no practical idea of perspective or anatomy or anything, really. I still don't know either too well, but I'm working on that.
Hehehe, it always makes me laugh when people call him a kid, because he's totally an adult.

Thanks again, man!
EDIT: Okay, I've gone on to draw the rest of the page, making it one scene instead of a collage of a whole bunch of images, which is where I thought it would go.
I did notice that I need to change the shadow of the upper left cloud, which is currently directly underneath it, suggesting that that cloud is not up very high at all, and also not going with the rest of the image. I drew the outline of the shadow some unseen cloud at the bottom of the page, though I suppose that could be the shadow of that upper-left cloud as long as I erase that other shadow. Do you think that would work?
