Think I've seen the Calico in a game before, not sure.
And from my knowledge, any game where you can reskin stuff has stuffloads of skins
Counterstrike more specifically, but the stuff I've listed I have yet to see that
Anyway
Like shell said
Picture 1-Pistol needs work right there.
You've connected the vertice creating that triangle which shows up quite brightly.
Why not make the entire pistol the same width, save a few parts, such as the top slide, which could be a wee bit wider or narrower, however you want it.
Picture 2-Sniper rifle needs to be fixed a bit more
That grip on the sniper, is too long IMO. If you shortened it to the length of a pistol, or used a reference picture to aid(NOT completely base) the rifle off a stock-like grip, it would look a lot better.
Width of the sniper should be consistent, and if you do end up using triangluated areas like that, try using smoothshading, to hide the edges, then smoothgroups to keep it from looking totally bad.
Picture 3-I know I'm being redundant here, but that flat top doesn't go well.
I suggest just extruding the entire top, raising it up a small bit, and narrowing the width just a bit to give it some slope.
It's just too sharp
Picture 4-I think this is your best model, but it too could use some work.
Like the shotgun, it's a bit flat on the top despite the rails
Rails are okay, except they are wide as the gun itself.
I'd make them 1/10th narrower than the gun, allowing for the holographic sight not to completely override the edges of the gun.
That area on the stock right there where it terminates into the gun should have a plate instead of the gun supporting it.
Like the UMP-45's skeleton stock.
Good God that took a long time
ARX-looks too bulky IMO.
EDIT-Yes, I am suggesting beveling some stuff, but not to the point where it looks so bad that it's not worth using.
I'm suggesting it to a point of....There's this point of beveling where it looks good, but it varies from model to model.
