Cool stuff. The arrangement on the base really tells you it is time to run! The brushwork is very nice and especially the teeth provid good contrast to guide the eye. Are squigs always red? If so forget about it, but if they can have different colours it might be an idea to have some blue, green and yellow ones in your next batch. Finally the red might benefit from either one more highlight or deeper shadows, just to bring out the detail a bit more.
However, generally speaking a wonderful unit with lots of charcater. I always loved the crazy ways of the Goblins.
