some shots are inaccurate, but it's ok!

Hey, Gospel, I have something to help you out a bit. Don't create a bunch of great stuff and upload it all at once, otherwise it'll all be on one or two pages. Give it a few days or so between uploads, so people have the chance to take a look at each one individually. Your mechanisms and guns are really cool, and they should get the recognition they deserve. Uploading everything at once kind of makes the scenes seem like spam (definitely not saying they are. they just appear so).

Try uploading regularly, such as once every two days or so, or maybe a little less frequent, to allow people to take a look at each scene. Make sense?

anyways, great gun, and you'll get better over time. all it takes is practice, research, and a little bit of adjusting those densities to make things stable 10/10

Phil is right, your scenes are very inventive but most people (including me) surely couldn't see all of them.
I guess that you have lots of projects at one time, don't you? Personally I focus on one scene until it works at the lowest frequency possible (100 Hz at best).
Just practice. If you focus on making a real gun with a pretty skin and realistic mechanisms, maybe you'll turn out to be pretty good! I didn't have a clue on how guns worked but dissecting scenes from other people (especially ngphil and yuras12) helped. Try if you don't

10/10 well deserved
