WATCH OUT BOYS HE'S GONNA CURSE YO DIIIIIIIICK
Jokes aside though, you should put in some time to get your curves down. You have a lot of really jaggy chunky lines here that could stand to be cleaned up a bunch, most notably along his sleeve there.makes it look less like folds and more like strange patterns in the fabric, doesn't quite work.
Also for folds you need to tweak the "outline" a bit so that it matches the lines of the folds, as you've drawn it parts should be sticking up that arent around the tops of those lines
