Please, take these redlines with a grain of salt.
If you're going to draw abs, I suggest you either have some basic thin lines ready before you complete them with shading, or that you find other ways to define them. Thick full lines will make it look stiff and unrealistic. Also, there's many types of six packs if you're going for those. The best advice I can give you is to look up refs. Just search for 'male torso' in google and you'll find plenty of refs.
Also, you were really overcomplicating the pants. Depending on how baggy the pants are, there can be many folds. However, you make it a little easier on you to draw the folds where they're most likely to happen. Not really a critique, but more of a tip. c:
Oh, and another little tip: draw the head first. Drawing the head in later will cause issues and frustration. You can always edit the sizes and whatnot during your sketch stage so don't worry about that, but if you draw a torso first and then the head, it's gonna give you a headache.
I'm not sure how you started on the drawing, but I like to build up most of my drawings in this manner. With circles where the joints are and overall smooth shapes to define the limbs. If you work with circles and ellipses, it gets a little easier to connect things and have your body look nicer overall.
Hands are also hard, so have these:
