My perspective skills weren't quite there yet while I was doing these. It's always interesting to look back at old work. The mistakes scream at me now, but that's just the way of things.
Maybe you're just assuming things are square and right. :P Sometimes too perfect can be too perfect. There are artists that can draw photo-realistic drawings...but why not just take a picture? Other than the therapy of drawing...
Weeeeell, these are still a pretty long way from looking like photos and having correct perspective would probably(at least in my mind) make them a little nicer to look at :) But yea obviously it didn't bother me enough to actually fix it before posting them here so there's that.
