Thanks a lot for the quick feedback Kurt
you are right about the ear, it's a seperated piece. I didnt want to merge it with the head till i finish texturing. i just need to combine the low poly pieces then smoothing will fix problem i guess. anyway it's not hard to fix it.
I'd like to hear about the texturing also please.
Thanks you very much.

edit: Here is some wires of the model before smothing. sorry for posting a lot.
