Alan,
It will take a while to tie them at the start, you have to think about what your trying to achieve and the techniques required, you will get faster BUT concentrate on technique not speed.
That's a better picture to see what is going on.
I agree there is no doubt they will catch fish so already you're off to a flier.
Nit pickin' again................. Thorax on the right is fine, thorax on the left is a bit short, easy fix though.
What have you used for the body? Black tying thread? Black floss? The body appears to be knobbly in some places, try to keep the body uniform which can be a bit tricky but stick with it.
Nicely done. Are you planning on using them soon? Post a picture of a fish if you do.
