I love your work, but the only thing that bugs me (this is probably just me) are the faces on the units.. I am a fan of the vanilla faces, as they fit the model very well and look good. Custom faces (this is in other mods too like RS2) just don't look very good to me. Maybe try putting vanilla style faces on some of your units and compare them to how they look now, I have a feeling that they'd look better. Again, this is just my personal opinion!
