Also, your chain guns look really nice.
I wish I could make things like that, but good old MSPaint just makes it too hard for me.You have almost good sense abiut shape, now just pay attention to details and make some shading to imitate, how in 3d reality this may looks. Not that bad, so try, even if results are by long and hard modding attempts because you has a chance for it, maybe not for superior pixelart but even good. Good training is to see how Doom and another game sprites are shaded then look at default Soldat weapons, later at some modern mods then compare and find your way to shade.
