No worries. I've been on less lately too so I understand. The video on this site gives a better explanation of how it works than I can. The gums is part of a shark bite for sure, but not the part I was focusing on. 
It's a pretty cool video for reference of the eyes, but it's pretty educational regarding sharks too! 
((gosh sorry for the late reply; I'm never really on here!))
Like a shark biting down? Could you possibly send a gif? :) I'm getting a feeling of exposed gums :0
And I might make a board in the forums one day, thanks for the advice!
It's all good! I bet it would make a neat animation of her eyes switching back and forth between white and black. Maybe rolling back white like a shark biting down. As far as the fabric goes, just start simple. If you're having trouble you could try to make a thread in the forums and get some advice. Either way, I hope you finish it sometime. When you do, pm me so I can check it out.
Awh thanks! :D She was meant to be UuU she looks pretty cool with whites too though ;)
The whole thing looks bad ;-; mainly because I don't know how to shade fabric llolololl OuO)b
She's great albiet a little creepy in the eye region. 
. I assume she was meant to be that though. I agree about the palette being very pleasing to view. I'd love to see the whole thing. Tell your sis she did a good job too.
I did actually add some purples in later! :P Not to balance it though, but because she was holding something purple, so thanks for reminding me about color diversity!
Thank you!
This is really good especially the hair and the color palette is balanced overall
the only thing I can suggest is to add some dark blue's or purple's in the darkest most areas
instead of just brown, a little color diversity can go a long way
but hey what do I know
OH GOSH that is the coolest thing @o@ I might talk to my sister about it, or put it in a water/sea-OC :D I didn't know sharks did that?
Thank you for the video and idea! :O gosh I can't stop thingking about it X)
