This turned out really well and I am very happy with the final result. Shading is a little rushed though... This motivates me to make more vector sprites. I might think about making the AK74, but with beige polymer features such as the handguard similar to MW2 2009. I guess the problem as to why I could never make vector weapon sprites was that I rushed and overthought the process. In summary I was lazy... Could use this for Fire Line Fury... If you are not X3x7_ then you weren't supposed to see that teaser/hint...
