In fact I consider this a 7.8. You have improved in a number of ways with each figure you post. This one is showing better brush control and accuracy, as well as better use of tonality on the skin. There are still a few points where you can improve, such as the quality of the work on the hair, (a minor issue), the removal of the moulding line on the figures left hand and perhaps the smoothness of the blending of the trousers, but overall this work is a good piece of painting and does show your improvement. Nice One James.
This one is the neatest of the three grymns so far. You seem to have kept the colours in their respective places properly. The skin, hair and armour looks pretty nice. The eyes look a bit mismatched, though, one looks straight ahead whereas the other one looks upwards it seems. I also don't understand why you painted SENMM on the armour clip? I have never ever seen armour clips in chrome and I seriously doubt that someone would use one in combat, since it will very easily expose your location. Furthermore, the horison line should be horisontal if you still want to have a chrome ammo clip.
