Cyber Coilgun

My final project for 3D Modeling 4 Game 1. Professor claims it was my personal best project of the semester. Here is hoping to more improvement as I go! I used a reference from concept art I found online. Unfortunately, I could not find the artist who made it. Anyone who can point me to the artist, let me know so I can give them credit for the original concept. The only things I drastically changed were the grip pattern and the addition of a red dot sight.

Modeled in 3DS Max, High-Low Bake in Marmoset Toolbag, Texturing in Substance Painter, and emission map in Photoshop.
