Here's a list of things I have changed that do not show up on this ref:
Age: now 16
Personality (slight changes): cold, mature, apathetic, slow to trust, alert, cynical, sarcastic, competitive
No longer weakened by the cold (but he still hates it)
Old spear replaced by "makeshift" spear
Lower half larger, legs more to scale with spider body
About six feet when in ordinary stance
Unnecessary belts, straps, and buckles because why not

I have also been learning a bit more about spiders in my spare time, so here's some info that effects Raven's bio the most:

A spider's body is filled with a fluid like blood called molymph, which essential for movement. In order to extend its legs, the spider pumps the molymph into its legs through a process called hydraulic pressure, which causes the limbs to move - sort of like a piston. Because this fluid is so vital to the spider, any blood loss will greatly subract its movability and reflexes. Thus, Raven is very cautious when it comes to combat, because he would become very vulnerable if he were to lose blood. The spider's body is also soft and easy to puncture, so he generally avoids fights. Malakai was an exception, because Raven was confident that the much smaller boy was not capable of harming him (but he had second thoughts once Malakai pulled out his daggers XD).

Oh mai, he looks awesome! I love his design! I think you did an amazing job! ( b'v')b

Lmao that's awesome! And I learned something new today! Also I was using his old ref for the drawing I'm working on. Guess I'll have to tweek a few things, although I already started coloring. Epic new Makeover!

So awesome! :D

ah! hello again!

Re: thank you! :D

Dragon with 4 wings are my favorite ^-^

For some reason whenever I look at Raven I feel less afraid of spiders xD

Nice redesign btw! :D

Re: really! Lol I have no problem with that they are for a crafting tribe and I think they be quite a few dragons like that ^-^

This dude is so awesome! :D i adore his desiiiiiiggnnnnn

Re: heh, thanks :3

This guy is sooo cool! I can tell you really tried on his design!

Re// You are now the bravest person I know ;>;
when it comes to getting rid of a spider I grab nearby rocks or shoes and start throwing x'D

But Jumping spiders

Those are the ones I scream and run from the most.
Regular small spiders don't worry me at all but expect daddy long legs (<- I think thats what they're called) makes me die inside a little xD

Yea its one of my better pictures although the outline was traced the face and everything else was drawn from top screen reff i was using but i'm glad you like it : )

I just noticed how one of your tags is #HOT lmao!

Speaking of makeshift spears I almost forgot Raven took Sirirus's staff as one

I do this for winking ;)

Awesome! CX I love the complexity of his new design and how he's even more 'scientifically accurate'! XD And don't worry, I also tend to adorn my OCs with useless trinkets!

Fun fact: A Spider/human taurid is usually called a "Drider"

*So says the internet.
