Spliced my reaper's face onto a body. Displacement seams are little rough but should fix itself if you print it. Some screenshots of the 3d model were put as a displacement map on a low-poly mesh w/ subdivision modifiers.
Its 1.5 million faces so it may not be friendly to low-end hardware (I know it takes a while on my Dorito Chipset) so I'm gonna slice it into easily managable segments over the next few days.
Turns out the Reaper Leviathan is about 3x longer than my model, but I figured it has more of a Cetacean bodyshape than a seaserpent so a stubbier body would be okay.
