Heres the GDI Grenadier. The biggest problem with this one was keeping the same camo pattern on the pants as the GDI Soldier without having to completely recolor the legs. I used the opacity tool set with a dark gray blue color to overlap the yellow texture to change it into a green, then a dark-gray overlay to make the legs a darker green so that it would match the pants of the actual character. I will link a few pictures to what the character looks like.

i will probably come back to this another time for more polishing like the others.
