Quoted from mayuh:
First of all: Awesome work! Detail, proportions... great!
CMYK ist the worst - true... That's why I only trust conversion and ripping to the most experienced people. I won't do RGB->CMYK myself.
Try "US Web Coated (SWOP) V2" to convert. That one works for the translites I do pretty good... honestly I don't know how much CMYK magic our printer guy does when he gets the files... my guess is A LOT
Before reading this thread i had the same thought as far as a "color correction" goes.
Great art. Have to follow Scotts vision on this one.
