Opinions are welcome, as I'm really feeling unsure about designs like this and I really want some input. Is it good, horrible, am I on the right track?

The link leads to the folder that contains the image, and anything else I decide to add there.

I've been toiling over these designs for a while now. I'd been able to come up with a couple interesting heavy-duty weapons for this mod long ago but wasn't looking forward to trying to come up with something for "small arms". Something about it just seemed far more difficult. I'll probably post links in this thread to new images as I create them.
