Seriously, coolest tutorials ever. More playing around produced these four (pardon the lack of LJ cut):
1)

I kind of like this one, but the silhouette actually just... wouldn't look right. It needed something along the outside to get rid of the roughness, but nothing looked right. Alas. The comic book effect was cool, though.
2)

This one was actually much simpler than it looks and than the previous one; I like the effect a lot.
3)

I learned how to make a brush in PhotoShop! Go me! Figuring out what she was talking about on the tutorial took awhile, but I got it, and I like the outcome.
4)

My favorite of the four, and I have no idea what I did. I followed the tutorial to get the dotty bit, but couldn't figure out how to color it at all, and ended up just fucking around. Somehow it colored itself to look awesome, and I love it.
(Reminder: the tutorials are
