Hey SJSUSPARTAN! I LOVE your reach forearm. It is a pretty smexy model.
But after looking at that and then comparing it to the live action Kat costume AND some more in game images of Kat, I noticed a pretty big difference between the models. I actually already edited your forearm model since there is a lowered area in the front and back of the forearm and I went through hell trying to edit that thing. After I was happy with it, I unfolded it and printed it out, ONLY to then notice that it was still wrong compared to Kat's forearm.
To give you a better idea as to what I am talking about, you can look at this pic:
The red lines are your forearms and the yellow lines are the ones from the live action. You will notice that there is a pretty big difference. You can't see too much from this view, but if you compare other views of your forearm and this one, you will start to see a lot of differences. And most of it is this area. I would try and edit this myself, but this is a pretty big edit and just to get those little notches were a pain for me since I hardly know what I am doing. XD
