Its def getting better, I'm just trying my first head model, the thing that I could suggest (and its not me really its Jay's suggestion to anyone) is to get as much reference as possible, especially if you want it to look good.

Also try to have a look at other peoples wire frames to get a good understanding of creating flowing geometry as, to me, it looks a little bit "blockey"

As Gohan said keep to modeling before going on to textures as other than jumping about you will be changing the geometry that the textures sssigned to, which could possibley end up in you re-creating a texture that you spent quite a bit of time on.

Hope this helps in some way

Keep at it
