Another paint scheme and another patterning concept, based on a crustacean that is equal parts vivid and dangerous.
I find that the colors and patterns found in nature can seem every bit as alien as the creations of sci-fi artists, so looking to real-world examples for inspiration can be useful even when painting fictional monsters. Here's one example.
Total paints needed:
-White Primer (I use Badger Stynylrez)
-White (I use VMC Cold White)
-Black (I use VMC Black)
-VMC Lime Green
-Army Painter Red Tone
-Army Painter Blue Tone
-Army Painter Quickshade Wash Mixing Medium
-Army Painter Green Tone
-Varnish (I use AK Interactive Ultra Matte)
