Ghostrider87, may i offer you some advice? first off, when people critique your work or dont like your drawing, take it into consideration and work on those things so that they will like your drawings. dont just keep doing the same thing you've been doing or people will never start liking them. i think if you practiced you could be a whole lot better. i think some of your drawings of batman and gambit have a lot of potential you just need to take more time on them and draw lightly at first so when you erase you wont see the first marks. also, i really dont like when you color your pics in marker because the colors bleed on to each other, its really dark, and you dont get any value. so you might just want to stick with pencil or another medium where you can practice shading.
so just work on some of those things and you will start to improve
