Hey Scott....that's not bad. Pretty decent masking on the hand of the guy who overlaps the speaker. Pretty funny idea. Whadya think about the same thing with a Maggie? More of the 'monolith' look?
Feel free to PM for any advice. I've been doing this since Pshop 2.5 beta (before layers)
In case you're interested, the best instructional book out there is Deke McClellen's "Photoshop Bible" IMHO. Not the easiest....but if you need to do something...Deke will show you how.
Russel Brown's website is good too. He show's a lot of stuff that I thought I'd invented on my own.
