i think what you need to do is have a WIP thread. This would be a much better way of learning rather than not posting anything and not hearing opinions on your work as you go along. by having a WIP you can improve on things you may not notice. it is also a more professional way of working. People in post production or games studios don't work on something without some sort of feedback.
Even with the crits one thing I do know is that I know how to model
no offense, but I'd like to see more of your wires before i agree with you there. you're not lacking in confidence!
