Tutankhamon's Golden Mask - the Cobra

Yesterday I painted the cobra (well, the tail is yet to be painted). It is 7,5 cm or 3 inches high and took me three hours. My miniature brush which had about three hairs when I bought it now seems to be down to two... Maybe it is time to buy a new one LOL :D. The detail photo is slightly blurry but I hope it shows some of the level of detail necessary for this painting.
