Thanks dudes,
Schmung: Already rescaled now, I've checked the checker and there's minimal stretching. I can't ever get the high poly into max so I've been using Mudbox to bake out the Normal maps which is pretty decent if you play around with the settings.
Where would I look for the Vidcard Temps and how would I know if they're "cooking"
Benjyshwa: Thanks for the critique. My character turns didn't quite work out as well as I'd hoped, but they were good for a rough guide while modelling. I also modelled the mouth open so I could rig it up with a morpher later on. More to the point though this is supposed to be a hyper-realistic/cartoon character and therefore will never look exactly like a baby elephant. However, having looked at him I do agree with the lack of neck and the head generally being too big.
So I've scaled the head down and moved the bottom of the neck up, along with more changes to the legs which I've made longer. I'm pretty happy with the changes and there's minimal stretching.
Here's a few screen-shots with a tester 1024 normal map applied to the edited model. There are some errors in the normal map but the sculpt isn't quite finished and I haven't done my usual clean-up to it in PS as there's no point in doing so.
Any more comments/critique is welcome as always.
