simon bisley its my favorite ever, after him on second place i would put alex ross those two are the ones that i worship
there are many others that i really like but not in the same way as bisley/ross because i would buy anything with their work on it, but it's not the same thing with the others, some of these are (in order of importance):
-jim lee (mostly because of his work on marvel)
i would also like to say that while he isn't one of my favorites i really dig the stuff from Ed Mcguiness too
i think it's interesting at least.
now what i don't understand is how people can like steve dillon! i HATE
(well not really the guy since i don't know him in person) even more when he draws the punisher! but like it was already said here "to each their own"
