This guy is going to have so much detail on him it'll probably need a fair bit of geometry to hold the displacement map (if I do decide to use that and not a normal map) so not really worried there, and it won't be too much that animation will be out of the question anyway.

Here's a smooth preview wire of him, can't be bothered to show the unsmoothed as it won't ever be used at that level anyway so it would be pointless.
