The heads look a bit to long and a bit to thick. A fault/problem I used to have (and still do sometimes

) is I just can't stop myself wrapping the stuff on. Often trying to use the thread to cover something I'm not happy with and make everything ok. It does not of course, just makes for an unruly head.
Now I tend to go the other way and often struggle to get the head on without covering the eye

.
I notice when the pro's tie on dvd they tend use few turns for the head. It's all done very quickly and without loadsa wraps. If the tying material is in the right place when you come to finish i.e. close to the eye, then it's simply a matter of 3-4 times round and done.
Try leaving a small gap for the head, finish everything much closer to the eye and aiming for a small head consisting of a max of 4 turns. If it looks decidedly to small I build it a bit with the whip tool. Trial and error really.
The rest of your flies look good.
