Bit of advice/critcism.
Your modeling skill is pretty impressive, the amount of detail is quite nice, yet I can't help but point out how some parts of the models are off-proportion.
The way the magazines curve down doesn't make it look good, it should have the back end of the magazine curving with it.
The Beast Master's tube magazine is too small compared to the barrel, making it seem like a toy in my opinion.
The 9mm looks okay, except for the wooden grip which slants off at the back, and I think it would look better if it was just one straight rectangle instead of that.
The SRCS punisher's grip, it looks like a henry lever action rifle sprayed black, then attached to the main gun; I feel that if you brought down the stock some more, or made it curve more like an actual rifle grip it would look slightly better.
The MP9N smg is where I was mentioning the magazine, it's just too flattened out at the bottom.
Last thing I've got to say is the MP5 SMG, the magazine is too thin length wise, and there's not enough segments to make it curve. The barrel is actually in the wrong place, it's more something like this-
Unless what I'm looking at is the barrel, and the top is really small, or something like that.
