Yeah, that's shaping up nicely. I think with most insects and arachnids alike, the legs actually attach under the abdomen. Where as this appears more like something you would see with a crustacean. Like a crab. But as this is a custom critter, I doubt it's going to matter. Also, the back section of these sorts of insects/arachnids is usually a lot bigger, usually even bigger than the front section. Though, again, I guess this is up to you.
Nice work.

"Earth? Earth-with-nuclear-weapons Earth?"
"Yes."
