Urubutsin character head

I have created the head for the character urubutsin in the final animation using mudbox Im not overly experienced with it having previously only done quick tests and general messing about with it in the past however i am fairly pleased with the finished head.

This was actually my 2nd model of the head as my laptop crashed soon after finishing the model the first time and the file was unfotunately lost.

Here is a render of the model after a bit more detail had been added and also painting the textures onto the model. This was actually again my first attempt at texturing in mudbox aswell and again I am pleased with the quality the of the finished head.
However there are a few issues one being the loss of detail the closer to the tip of the mask this was simply due to the fact that the model began as a mudbox basic head and I edited it to this shape and because of that the topology caused there to be a lot more divisions at the base of the head than the tip. The second issue is the polygon count which i will need to reduce through retopologising the model and baking the textures to make it suitable for animation.
