The color choices are good (I like them anyway) but the \'nids could seriously use some shading. Try a Future wash with some heavily diluted charred brown (GW scorched brown?) on part of one, just to see what it will do. I suppose the trick will be to wash/shade without losing the main colors, because they really remind me of some insects I\'ve seen.
Nice work overall, and I\'d love to see that army on the table.
