I do remember those old Mega-Man NES box-arts. But that's not the Mega-Man I remember seeing from looking at Mega-Man 1-3's box-art. Mega-Man actually was holding a lazer pistol in his hand. HAND. He didn't even have a mega-buster. Looking back, i find it quite funny how the artist didn't even know what Mega-Man even looked like.
I know you probably won't read this due to the amount of artwork you post here, but seriously, that's not that stupid Mega-Man cover-art that I remember.
You shoulod do a second one, only this time, you get the character design right.
