Getting better mate... definately getting better. As you say, its all about practice, but its also about each artist's unique style. No matter who carves these, or how talented they are, each person always leaves his/her own style on the project.
Have a few more goes and maybe print the posts I've sent so you can refer to them as you go. Make sure you have the initial two eye planes steep enough so that the face has a rounded look and not too flat in that area. Also, maybe push the mouth plane down a bit. This will give you more area for the eyes. You can make your eye socket 'scoops' come further down the face. The bottom of these scoops define the top of the cheek bones.
The key to clean looking results is making sure that the two component cuts meet up. This means in essence that the tip of your knife on your second cut, buried in the work, must meet up exactly with the place where it was on your first cut. Since all this is buried and you can't see it, it takes a bit of practice to get the feel of it. Sometimes guys who use chisels a lot struggle with this because its not as big a part of chisel technique as it is for blades. Guys who use blades all the time, learn this early, or their work tends to look 'fuzzy' where two converging cuts didn't meet up and the chip was broken or scraped out rather than falling out cleanly.
Its bloody hard to discribe in print,:~ but it is the key.
If you want to, post a WIP and then maybe I can comment in more detail. Its sometimes hard to follow exactly what was done just by looking at the finished product.
