He certainly looks good mate..the eyes look good. Its hard to tell from the net images but does his skin have a greenish tone to it??? ( I should know my kids have watched them all 50 million times). The only thing the images seem to have are veins showing through...are you going for those as well (i.e colour)?
Other than that it looks pretty damn good mate...well done
