Here is the start of the overflowing blood, once I finish the surrounds on the lower half, I will add water effects mixed with black and red ink to get a really good blood effect which I will pour roughly over the skulls and the blood there to 'smooth' it out and make it more gorey, this is just the interim, I'll try and keep you all updated!

. The blood I did using a hot glue gun, greenstuff and pva glue. Greenstuff to make a layer to help get it to flow where I want it and stick, then the hot glue to get the sheets, finally pva to smooth it off a bit.
