give it a personallity
there are all those clans like the glocks, the clocks and the locks.
it's allways nice to be apart of a group but people are getting tired of seeing them. at your work "even if it's short" i can see you have great potential and are a great artist. but you will not be appreciated as much as you would've been if you'd make a unique character, a standalone, with a face instead of a gun. it's just a personal advise, i don't expect you to follow it up (lol), but just make a unique character, with an own story (, a face and a voice) and with your drawing capacities, you ONLY will be getting positive replies.
good luck
