Relax. Not everyones gonna like everything you do. You cant get better if you cant take criticism. Dont post it, if you dont want people to comment on it either. Just make something and submit it to mohfiles or AA and let the d/l #'s speak for themselves.
Try to go a little easier on yourself. Like you said, you are new to skinning, and you don't have as much experience as some of the guys on these forums liek RF and guarnere and brutal (there are others). These guys have been skinning for quite a while and you can tell that it pays off in their work. Keep at it man and don't give up.
Yeah calm down mate - Not many ppl like the ones i posted on this forum but I make em cos I like to and Im learning - I'm still deciding whether or not to post my map though lol
