so go get some skills
try to model something different. try to make a gun or other prop for your game characters. then you can apply whatever you have learned to you next model. I'm still an amateur, and I tend to get stuck in certain areas of modeling, but I just move on to something else, and eventually, i'll think to myself, "hey, I know what I was doing wrong before" and then I can go back and finish what I had started.
just keep learning
