This came to me in a dream. That's not a joke.

One thing you may dispute is the Perception check since many spider actually have pretty poor eyesight (and some have no eyes). That's fair but this is based on a jumping spider. If you want to move around what type of spider you are using, get rid of the Octoeyes feature and put in one of your own. Trapping spiders or highly poisonous ones could make a great addition. Up to you!

The other point is that you could technically use any other half-celestial (can't use the name) subspecies for this species as well. This lost the Healing Hands and Light Bearer abilities for Spiderstep and Bittybite. So you could easily substitute the Dexterity ASI and Web Wings for another subspecies.
