Photoshop newbie.

Lately, I've been working on my Photoshop skills.
My skills... are pretty simple. I can make cool eggplants! I want to become efficient, ya know?
I have CS4 and I think I'm doing fairly well, so far.
ALTHOUGH, it likes to fuck up and crash and freeze from time to time. But I didn't pay for it, so I won't complain much. Free.99 Honey.
Sure, I should get CS5, it's pretty much the same thing, but I've devoted a lot of time downloading and installing brushes and shit on CS4.

I'll get stick to my habit of skipping four or five versions before I get the latest.
