This is a different take of a Vahki appearance, but still pose a treat from your mentioning.
I like how the “feet” can flip for it’s transformation and the torso is very conventional.
Nice redesign, but it the lack of the mandibles from the original model and the, err, odd stance of the spider mode bug me (no pun intended i swear). They’re just nitpicks though, I can’t find anything really wrong with it. Nice work.
