Thanks for sharing this. So, to start, the scene has some issues. It looks like a piece of concrete is ramming Batman in the jimmie.
This and the general layout of the buildings makes me think you could use some practice working with perspective.
There's issues with proportions all over but one big anatomy thing that sticks out is that the forearms and shins on Batman seem to have been hit by some sort of rubberizing weapon. Unless this legitimately is the actual thing being used in the story you need to straighten those bones back out a bit. This and a few indicators in the structure of the head make me feel like you could stand to study up on construction technique for building up your figures. This is the bread and butter for learning and I think if you were to look into George Bridgman's book(s) you would do yourself a world of good.
Think of the skeleton underneath. Think of how the forms comprise the arms and legs and the "mechanisms" of those joints.
Having said that, your linework is clean and your use of line weight makes me think you'll be a good draftsman once you get a handle on perspective and the anatomy work I mentioned. Thanks again for posting!
