FREAKAZOID!! I've spent the past hour in school watching Freakazoid XD
Other people on here have cosplayed Freakzaoid, so try PMming them?
Seeing as it's only your face you'll need covering, I would go for body paint, rather than airbrushing. Kryolan Aquacolour comes highly recommended. So does Ben Nye, but there have been reports of that flaking easily.
White boots that fit close to your leg like that would be very hard to find I imagine, so probably your best bet would be the make bootcovers out of lycra. You can find boot cover tutorials on here.
All the skull, John. I ACCIDENTALLY ALL THE SKULL.
Upcoming cosplay: Black Swan
