Dude, dont make a scene. You're taking critisism of work as personal insult. Nobody is insulting anyone. Saying that someone pointed out 'twisty' arms as your only helpful comment is rubbish. People are trying to help you by telling you proportions are way off and the topology is weak, you're underrating their opinions by 'going along with it anyway' so you can hardly expect other people to be jumping to help.

If you want to do well at 3d you'll start listening to and appreciating the crits and comments you get, the community here is actually really quite friendly and helpful.
