Hello,
I totally understand what you want, I have a keen knowledge in illustration, using both Illustrator and Photoshop,
First of all I'll do 2/3 sketches, then after approving one of them I'll start Inking it using Adobe illustrator since Victor has clean lines, then convert it to Photoshop to do the magic and coloring,
if you want them as photoshop layerd, i Can provide that, please tell me what size of the art piece you want,
contact me for further questions,
-Sandra ^^
