When I create a pattern or ty something for the first time I try to exaggerate some of the features of the bug I am trying to imitate. For crayfish patterns that includes the claws, eyes and antenna. Now exaggerating doesn't always mean larger, I just want the feature to standout more and make it so no one looking at the pattern will have any dough what is the claws, the eyes etc. In fact I prefer the claws to be smaller and not equal in size to each other. It makes the crayfish look more defenseless and easier pray for Mr. Smallie, I think anyway. When it comes to color I want a dark pattern and a light pattern in the box. I also try to use materials that will have some motion even when the pattern is at rest as I find most takes on Crayfish patterns happen while the pattern is at rest. Hope that helps you out some. Remember there are no bad tys but there some not worth repeating.
