5/5 :D I think that you are in good way to be very good :D Great particle designs, minimum of not detail-heavy parts. If I may, try to study anathomy of creatures you are trying to mimic ion your works. Nature as its stand alone is the best inspiration in sculpture art :D
WVery well-made head. I would try to make the nose shorter or fill it up with something, but this actually works very well. It actually connects well to early legends of dragons, in which they are said to have beaks. You still need experience for wings and legs, but I am surprised that the body and neck actually look this good, considering the techniques used. The tail is not bad, but does not distract from the good parts, as do the legs and wings. That is probably good, but it is actually a bit harder to notice and with it, see as a whole. In conclusion, I like your dragon a lot, but it still needs work and you are on the right way.
