CG - Boys will be boys

Wow, i finally submitted something X)
These are four of the characters of a new comic I'm working on, ChromosGen.
From the top left, clock-wise: Rowan, Leroy, Niko(laj) and Xander.
Goofing around while their picture was taken

I'm planning to upload the first few pages in a few days, as soon as I've found my scanner. (this drawing was photographes, I did my best to get the colors right)
I used my newest set of colored pencils for this one; Caran d'Ache pablos :)
I love their brilliant colors!
