IDW Art Du Jour Featuring Kup

IDW Publishing's "Art Du Jour" page is showing a sort of "making-of" series, starring Kup, who moves into the "Transformers Spotlight" in April.  First they posted the pencils for Alex Milne's variant cover for Kup's Spotlight issue.  Then came the inked version of the cover, and finally the full-color version with colors by Josh Perez.  Check out all three images here!
