They look fine and cosy to me.
Better warn you though as it hasn't been mentioned yet, hand shearing is easy when the wool is risen and there is a nice break to shear in but clipping through wool in the middle of the lock is not such an easy task, especially if you have no experience. Any shearer will tell you that even shearing with electric shears is a pain in the bum before the wool is risen. It's a bit like trying to cut steak with a butter knife, lol.
If you really feel you must take some of the wool off now, test your skills out on a small area and see how hard/easy it is, do they need dagging? if so that would be a good place to start.
Personally I would leave them until next year as they're not overly deep in wool and don't look at risk of becoming cast easily.
