Monster from the horror-themed, now barely functional MMORPG Requiem: Bloodymare / Memento Mori / whatever. Ten different poses.
Blender is able to import animation files for most models from this game, so more poses are possible if there is demand for them.
I have used the model's texture to add some detail to the low-poly model via displacement. Typical tabletop 28mm or similar size figures are fine like that. Printing at larger scale would require some further cleanup and remodeling. Printing at very small scale would require making important details more prominent.
