Top 2 is from Tradd Moore. Dude breathed life on the page.
Bottom is Jim Lee and there lies mostly my issue with western comics. The fight scenes are always progressing to the next story beat (which isn't inherently wrong) RATHER than a constant struggle between the characters. Which is why you always see Shounen shit have long fights with ridiculous powerups and asspulls.
For the artwork itself, it's obviously not bad but he's just putting them in action poses. Kind of like what Alex Ross does.
