Hey there Dark Falcon, not sure what you want, but im sure you would want some critique, so here we go.
despite of what everyone else said, i'm gonna go with a differ approach this time according to what i see and think,
so if it sounds a little bit harsh, please dont mind, critiques comes in all kinds of way, some are harsh and some
are easy, so remember that, alright lets get on it
Cmc - from what i see, you understand the basics of weapons and it's shapes - obviously. but when drawing these, have you study its lights and shadows yet? the shadings looks alright, but they're not in the right place, for example, the sniper, you can see that the light is coming from above which is why it cast a shadow right underneath it, but if you look at the sniper closely, it seems like the light is coming pretty much from everywhere, specifically i would say more like straight from the front as if, in this case, since the picture was drawn side away, it would be side. perhaps that may be what you're trying to do, but if it is what you were intended to do, i'd suggest you highlight a little more on the top so that it's clear, because the dark/shaded lines on top of it shows that there is even shadings on top of it which is makes it look like the main source of light is not coming from above anymore, like i said, more from the side way instead, and that may be for all of the rest as well, so if you can or on your next drawing, try to avoid that because it can make a difference :)
Thoughts - to be honest with you, i think you're in the right direction, just that you need to take it a little deeper and study more about it. I understand sometime you might just want to draw "the just of just" draw and draw whatever the heck you want, but i would like to say this that friend, if you just draw the just out of anything out there without inspecting it inside and out, you may draw a 100 times, but you will not understand why nor gain anything from it, because you simply just ignore the most valuable and critical thing of all, "study". why is it important? it's important because it gives you a meaning, an answer to understanding why everything flow and works together the way it is, that's why it's important, and that's what i call "Key", remember that :), so when drawing whether it's doodling, features, or practicing, you need to keep an open mind and be ready for it. dont just scribbles some figures and post it because you think it's cool, draw something that has a meaning in it and important to you, then post and gain the respect from the crowd, that's how a real artist is, but again, i think you kind of got this already, just need to work on it a little more :)
