Found this really fun image on Reddit and since I've already done something similar for the wood/ice swords (if you remember those), the decision to turn it into some designs was an easy one!
I don't do gun designs very often at all (more of a sword guy myself), but I actually had a lot of fun with these! Some stuff happened and I lost the file after overwriting it which sucked, but I was still able to get the drawing done in the end so it's fine :P
Anyways let me know what you guys think about these, and which one's your favorite :D
