You aren't bad, but maybe you are just overreacting a bit. I mean, you do have 55 fans, and you do get plenty of views, that's already something most artists here don't get. I'm not saying all the votes you receive are fair, but I don't believe they are truly unfair, for instance: http://www.newgrounds.com/art/view/safst3r/take-aim
This drawing of yours has pretty balanced votes, it's well drawn, and has good anatomy for the most part but has a little proportion problem and the shading isn't too impressive. a 3.33 out of 5 sounds pretty fair to me. If anything, I believe these mixed critiques should only drive you forward on your way to becoming a better artist.

Well, I feel you. Back when I was in the NGADM semi-finals last year, I received quite a bit of bashing for dreaming up an idea which wouldn't otherwise have been undertaken by anyone else. Granted, I didn't have the skill that I do now, but..... it was harrowing, it was painful...
I will take a look at what you have uploaded, and I may post a comment. But.... *taps your shoulder with fist* Chin up, bro. We'll make it through this.

Thanks, bro. I'll keep going, and with the fanbase I do currently have, I think I'll dedicate something to them for being so kind to me. *brofist*
