Oo I like it!

Those first two sketches are great, they remind me a lot of Picasso, especially the second one, which is almost cubist I guess...

The thing with abstract art is that everyone sees it and says "oh that's shit, I could draw better than that," but they actually can't. It takes a good artistic mind to be able to draw abstract stuff and actually make it look good.

I've tried a few things like that - every now and then I start to draw things, and just let the objects flow into one another, but my stuff always looks pretty crappy, I just don't have a very visual mind I guess... I tend to just think in words. Good job though, keep it up!
