Thanks everyone,
I really enjoyed doing this one so i'm going to start on a few more straight away

Smooth. I like it. He has a Labyrinth feel to him. I wish I could make green stuff do what I want like you can.
I use Magic Sculpt mixed with a little bit of green stuff, Its a lot easier to work with and smooth out.
Maybe bland wasn't quite right. I think the back looks a little unfinished. The front is great! Just. Some constructive criticism. 
No worries

I like constructive critcism, It helps me improve

Thanks
George
