good job, and nice to see the effort that you are learning modeling!
you might want to leave the handle/trigger open to add some more shape to the weapon so it will not look like a bottle so much.
also, maybe its just me, but if the bullet chain is at the front of the gun, probably with the shooting mechanics, i don't know why it has a so big body at the back. if there is something interesting happening there ( spooky liquid? :-) ), you might want to show it at least with the texture.
All very good points and I will add interesting things to the model at later points if all goes well.
For now though I'm focused on my mission which isn't about making a perfect game gun but simply to design and implement it. I am nearing the limits of the explicit original design now and so that mission is in fact nearly complete. The only part left that I actually planned for was positioning it on the human's hand so I'm going to do that.
I deliberately made the gun simple this time because I usually aim too high (no pun intended) with these projects and give up half way through. So I'm not just learning how to use blender as I do this. I'm learning how to make good plans and stick to them.
Still, I appreciate feedback on the gun as a weapon as I'm aware that this very-quickly-thought-out design has technical issues. Why exactly have a chain that feeds from the gun back into the gun?
I've tried to think of some reasons behind it other than 'because it looks cool', but I've not had much luck.
The best reason I can think of is that the chain is clipped on like a cartridge with the advantage of variable size and that spent rounds are tidily kept on the chain. The disadvantage being it's slightly more cumbersome and fiddly than a cartridge.
The grip and trigger have purposely been left out so far. For now the human's hand will just disappear inside the gun while I work out how best to position it.
