I totally agree with you! You know when you look at something for so long, you dont realise where it might look wrong!
Im really pulling my hair out on trying to remove the fur on his lips and it just wont seem to go away!
As for the tutorial, i think its a mixture of beginner and intermediate level of use. Its explained really well, although in some places i was slightly confused as to which hotkey was pressed but overall, i think kurt did a great job of guiding us through it. Its a great way of learning the various techniques in maya.
