Nice work dude. The bitz have been used together well, I would greenstuff some horns onto the skull on the left shoulder pad as its the librarian symbol.
I cant say I like the head. I just dont feel it. It just doesnt look right, doesnt have a psychic hood and (most importantly) Ive seen your past librarians and (although I might let if fly for someone else) I know you can do better.
As always you make the model interact with the base very well but there it something that doesnt seem to have the right flow of movement to me.... It took me looking at it for a few minutes to work out what it is but I think its the position of the staff.... The pose it is in (swept back) is typical of someone running (especially in a chinese martial arts film
) but the rest of him is only walking forward. I would say you could change the legs to be running but then the arm with the eagle wouldnt look right which would mean even more work. So so you dont have to change a lot I would re-position the staff arm. Possibly to have it resting on the floor. You could even have it melting into the stone floor a little to add to the interaction between the librarian and its base.
It sounds like Ive slated a lot but really its only two things. The staff and the head, I just wanted to make sure I explain why I dont like it and not be one of those failures that say they dont like something and then dont help improve it, you know who Im talking about
The rest of the composition is damn nice and coupled with freehand I know it will look great with a little work.
