Not only does artist Bill Sienkiewicz have an impressive pedigree in comics that includes things like Moon Knight
, New Mutants and Elektra: Assassin (with Frank Miller
) but he also has a very distinctive style.
His work is very kinetic but also (and this was particularly true back when he was doing New Mutants) much less concerned with photo-realistic portrayals than the industry in general.
So not surprisingly his take on Rocket Raccoon from Guardians of the Galaxy is simply stunning.
