Ugh, those covers are horrible! Too busy, too crowded, each too focused on a character it shouldn't be. And who thought it would be a good idea to shove the rest of the main characters into a single corner? The OT one is slightly better, and Darth Vader is certainly a better focal point than Yoda, but it almost seems like they forgot that Luke exists at all.
"Um... we're out of space! Where do we put Luke?"
"Who?"
"Luke Skywalker... the main character of the movies..."
"Oh, that son guy? Eh, let's just throw him on Darth Vader's cheek."
"Um... it's crooked."
"Sorry! Time to break for lunch! Print it!"
