to my own surprise it wasn`t to hard to get this octopus painted.
at first i covered the hole model with diferent bumps . then i flushed it with the gound color, a muddy green/grey. then i took a darker version of the muddy color and painted the puss with a alhateture-brush. after that i reapeated the last step with a lighter version. then i painted the downside with pale fawn.
