Playing with new brushes

I downloaded a bunch of new brushes from here..
http://myphotoshopbrushes.com/brushes/search
I particularly like this site because it specifies which brush packs are "Free for Personal Use" and "Free for Personal and Commercial Use."  I mostly stay clear of the ones you can't use for commercial use, unless it looks so good that I just want to experiment with it.

This is a picture I drew (straight into Photoshop) a few days ago..

And here it is after experimenting with some of the new brushes...
