That wasn't criticism at all, it was a "honest" comment.
He didn't give me any tips, he just told me it looked like absolute stuff.
Do you see ANY kind of actual criticism in anything he said? Because I sure don't.
And another thing, I DO want to be a modeler, but Ben Grapevine and Kishgal are just going to constantly hate on everything I model. Specifically calling it horrible.
I'd like to mention that I tried to offer some constructive criticism, so I don't really think it's fair to say you only got insults. Also, they aren't going to automatically call everything horrible, it's just that they will comment based on what they see. If anything, this should be an incentive to make a really great model and prove them wrong.
Bens most recent comment about the cardboard cutout is pretty much spot on, real guns are made in a three dimensional context, but it appears that this is mostly made from a two dimensional shape that was simple extended. Now, like I tried to say originally, this isn't too extreme with yours, since you've definitely got some z-axis variety going on, so to speak. But I think maybe a greater understanding of the physical geometry of the object you're trying to model is very helpful. I know that if I don't understand something, I'm pretty much unable to model it.
