This is how I look at it.
I don't care if I get a little criticism. The main reason for this site is to post your model and learn tips and tricks from others. For example: I get a cooment like, "Got a little glue on the windshield", I'd be fine wiht it. However, If I got a commment like "Looks bad because you got glue all over the windshield", I wouldn't be too happy.
If it's good enough for me, and I get rude comments, I don't care what anyone else thinks. I really don't. It's MY model, so I can do whatever I want with it!
