It happens to me too. In general, my threads don't attract much attention, even if my work is geting good, like my Tesse model. Patience. If people don't want to talk about, we can't force them. Just go on with your model, and listen the few dudes that come to visit you.

I think you should post your model on other foruns, to receive crit from more professionals. Try CGTalk, Cgchat and Polycount. Be warned, people on Polycount are specialized in game models, and they have no mercy doing crits, go for your own risk!

Yes, I intent to do much more chars. From now on, I just want to dedicate myself to low poly modeling. I'd love to work on games industry!

See you, man. Go on!
