1. Cut the spider legs off of Iron Spider's back. They're all connected to a square backpack thing, so it's easy to just cut that part off, keeping all the legs as one object. Be careful when cutting the backpack off to not accidentally cut one of the legs, as I did, but it's easily glueable if you do.
2. Cut off some of the pink effects around Psylocke's hands. I left some on just to be able to repaint yellowish green to give that bug-like poison effect.
3. Glue the backpack/legs right here on her back. It fit right into the groove as marked on the image, tucked up against the 2 folds in her cape.
4. **Optional, but you can also cut/trim off some of the hood that goes under her chin. The hood D'Vorah wears goes over her head like a jacket, not under her chin/around the front of her neck. So I trimmed some of it away so that you can later paint it yellow to just look like her skin rather than her hood. No picture here for this step, as I did this after originally painting it black and realizing it didn't look quite 100% accurate, but you can jump down a couple steps to see what that looks like.
4. Paint her cape, hood, shins, and bra/underwear section black.
5. Paint her face, forearms, belly, thighs, and feet yellow.
6. Paint her eyes and mouth black, and the pink stuff around her hands a yellowish green.
7. Paint the Ovipositors a blueish green(or redish orange as they've been depicted that way as well is you desire) combo and you're done.
