hard to judge from a single image vs. an actual comic

but what's important to look at for a single image illustration is clarity. if they be clear in a single image and its more than just a pin-up then they can be clear in a dozen for a comic
the splash image approach (which is what most comic books do) sucks for actual comics because its not a simple statement. it works more for movie posters or league of legends art (something meant to be seen dozens of times) but not comic book art

a lot of the good modern illustrators do focus on a simple statement and let the details be something you come back for, not something you fight against
