Custom """"realistic"""" character model for my game

I wanted to keep the desing of a R15 Roblox character in my game, but I also wanted it to have more normal sizes so i made this
(If you think thats too tall, there’s a heigh stat that is random generated when you first join)

It’s a small little proportion change, but what do ya guys think? What could be improved? Should I make it more skiny?
