Thanks for the comments, I'm going to get a membership for 3dsk as its a bit hard to get some good ref for close ups for various areas.
I thought that it needs some variation, which i'll work on, needed the crits and comments as its a first go.
As for the Tablet its a Trust one, I got it through uni, as ive never used one beofore it appears great, and its probably best to save my cash till I can get the best out of and warrent (If my other half lets me that means!) getting a really good one. It makes soooo much of a difference in Z brush and photoshop, dont know how I even thought of using zbrush without one!!
Thought it would have taken a lot longer to get used to it, its great so far!
