Yes, the facial features cannot be tuned, but this little workshop allows for a bit more freedom as to depict your "character". I have completed a new one for both my Xbox accounts and while it doesn't look like me in detail, it allows me to express my true self characterization a lot better so you get a better aspect of the real me. I have yet to see an avatar that meets my need, heck, my hair is down to my belt, and I am 6'2" tall, so my hair is nearly 3' long. They don't have enough variation on beards either, I wear a van dyke, but my chin whiskers are about 6" long, not close cut, but again, it give you a bit more of a personality. I wish they would allow for detail sculpting like Fallout 4 does, but not yet I guess. Still better than the old version.
