So far, none of these drawings are very impressive. So you people trying to "one up" him, you may as well keep trying, because your drawings suck. Either cuz they have too squiggly of lines, or just bad proportions (gloves are cheaply done on each one, cape is wrong, bat wings look dumb and color choices are pretty bland). For such a simple character, you guys sure know how to screw it up. The poster's may be small, but it's actually the least ugly of all of them, LOL.
It's not the program he's using that is at fault, which you guys are clearly proving by showing shoddy work. Its the fact that not much time and effort was put into it, which is what you guys also have proven. Simply just take more time and put more effort into it and it will look a lot better and when you post it, people won't be so cruel to you. Remember, you are showing something that anyone can just harass you for, so you really need to be sure that it won't be as bad by trying your best.
Edit: This post is mainly aimed at the ones trying to one-up the poster, which I think is very immoral. So main poster, you can ignore this post as it's not meant to offend you in any way.
