Jeff,
By posting something like that bust here, it will do two things. It will cause a reaction by seeing it, then an opinion. People are just stating their opinions because you posted it for everyone to see. More than half the people who posted here don't have your talent but they all still have an opinion. Thats not a bad thing and I hope you don't get mad at me for illustrating it again, but I don't think anyone put you down.
I see you're from Chicago. I graduated from the American Academy of Art among some other members here and we were fully encouraged to critique others work and have ours critiqued. When people see it they get an instant reaction and want to express their opinion since you're showing off the piece, and it's a fabulous piece! At school there were people who wanted badly to hear others opinions so they could get others ideas and perhaps learn from others and find ways to improve. Then there were others who just could not take criticism no matter how little was given. I saw grown men cry because of what someone said about a painting of theirs. I'm not kidding either. Now, I'm not saying you need improvements, I'm just stating my opinion on it as well as the others. Bottom line is if you're happy with the piece that's all that matters.
People will always have opinions on your work and it won't always be exactly what you want to hear, and that's not always a bad thing. You don't have to agree with everyone either. It may be best just to say, "Thanks for the suggestions, but I love it just the way it is cuz' that's how I want it.", and just blow everyone off.
Not an easy task for someone who takes such pride in my work.
All artists take pride in their work, man. But as artists, we must always be willing to accept room for improvement. In the end you don't have to take anyones criticisms to heart. If you're happy with what you're doing and completely satisfied with your own performance, then simply disregard all of it. They're just suggestions, man.
You've proven to many how good of an artist you are. Take pride in that as you should.
The reason I took the time to post this was because from one artist to another, I know how it feels to put so much of yourself into something. I just hope that you understand that not everyone has bad intentions and I hope you're not upset in my writing this. I have only the best intentions in doing so.
