Hi Robert, since you've posted on the brutal honesty forum, I assume you're interested in some (hopefully) helpful advice? Here goes. First I think it's obvious you can sculpt, but you say you want to find some proper technique. Well in my opinion you are doing things the wrong way around. I don't think you will progress very far without realising that a face develops from the structure of the head, so the best way to start is to build the head on an armature that you can hold and move around and look at your work from every angle as you are doing it.
On the sculpting forum there is a great SBS by Carl Ried about sculpting heads, and there are lots of sculpting tutorials over on YouTube that you should find very useful.
Also, buy yourself a good Artistic anatomy book. There are loads on Amazon, but my recommendation would be either Jeno Barcsay or Dr Paul Richer. A computer screen is fine, but there's nothing like looking through a real book.
Best wishes, Gary.
