Not to be rude, since I don't know you very well I'm not going to use your real name, but here it goes...
I know that I don't participate in DTB's (and I know I've been away for awhile), but I I'm going to add my two cents anyway and give my outsider's perspective to all of this.
BeneBaby, of all the people on here who submit photos of their work, I have to say that yours is one of the best that I've seen on here; and I think the rest of the people who frequent this site would wholeheartedly agree with me. I think you and I (and the rest of the board) know that you have more talent in your little pinkie that others do in their whole entire body...
Seriously, why quit because of someone's else's opinion of your work. I'd hate to see someone with your caliber of talent wasting her God-given gift just because a couple goobers didn't like what was produced. Quite frankly, who cares what they think? Does it even really matter? Come on now! Granted, people have different tastes, but I thought art was objective! If there's someone out there turning a lovely shade of chanteuse "just because" should not deter you from entering contests, posting photos, etc. etc. Who gives a flying rat's patootie! Don't let them take a big fat dump on your confidence because someone was on the power trip!
Quite frankly, I don't have enough appendages to count how many times I've been in complete awe at some of the things you produce! Not only that, but the tutorials that you create are pure gold! I also don't have enough appendages to count how many times a majority of the girls on here have BEGGED, and I mean BEGGED you to make a tutorial of something because they loved it so much!
Here's some food for thought: By quitting you're letting the airheads win, but at the same time you're taking away something precious from this group.
I would suggest that you think twice before giving up.
