I left these in their raw pencils and inks for the moment. Each one is inked just a little different. Groot, for example, is mostly inked with an ink brush, allowing for quick, random, natural thick lines and shadows. Rocket is inked with a Tombow pressure point pen, and Storm is inked with a Pentel pen, a technical pen, a brush for the fill and a white gel pen. I used a photo of an angry raccoon for reference on Rocket, and went off memory for the other two (except Storm's headpiece, never seem to remember exactly how to do that). Who'd a thunk so much goes into this stuff? Look elsewhere for the final colored versions.
