Thanks a lot for all the things pointed out!
I feel the same about the vinyl and scale thing, it's really out of it, and I would need to remake a few parts before putting this one back on again, I think the chest needs a few mods too.
As for the vinyl covering, I know it was my first try, and I did learn a lot about it! Glue is such an essential thing in it, The glue was way to weak, and after a while it lost it's grip on the vinyl and air came in, that's why it looks rather bad at some places, I really hate that part about the costume, and vinyl is really hard to work with. I dunno if I will keep using this type of method to make my costumes or if I'll look for something that I think is better to work with, but I will try a little longer and practice more! Though I like the parts that actually turned out good.
The scale was pretty off, and I think I need to change the structure a little so I can get better scales on it. Thanks again!

Oh and the reason The F 91 looks so strange, is because when the glue I used for that one dried, it messed up the PVC and wrinkled it, I was horrified by it and will not use it on PVC ever again, I couldn't remove it either, because I didn't have the time to remake the shoulders.

But next time! It shall be even better.
