The thing that bothers me the most about Rachnera's character design is that her human body and spider body don't really look like they're actually integrated as one body. Look at the MGE spidergirls, they look actually integrated, the waist actually goes into the actual spider body and looks very much so like one body, as opposed to Monster Musume's method where it looks like Rachnera's human portion is tacked onto the front of a spider body.
