You're doing wonderful work! You've discovered quite a talent. If I might make a suggestion: every now and again, you should hold your sculpt to a mirror. It's quite helpful when you're trying to create a symmetrical face. Of course, as many chuds will tell you, most faces aren't completely symmetrical, but at 1:6 scale, it becomes more important to get the likeness as symmetrical as you can.
Besides your excellent likenesses, the thing that is impressing me the most is our skin texture. You are getting very smooth and realistic textures, and that's often one of the hardest things for a new sculptor to master. I can't wait to see more of your work!
