The explosion in the background is still reminiscent of Duke Nukem, but the different clothes, hair and name definitely makes him a distinct character now. The girls' hair have also changed and I think the brunette has improved much overall (better facial expression and her clothes are more real and less chosen for the occasion if you know what I mean). The girl being carried has a more realistic pose as well, lying on Dude's shoulder instead of in it.
A cool poster with many improvements over time!
