Oh man look at all those folders and layers. I can only work with two at a time, otherwise I start to lose my mind.
It's very colorful though. I dig it.
The amount of layers I use varies alot lowest amount I have ever used was 3 (Sketch, Lineart, Base+Shadow, in PS, the actaul lowest number was actually 1~ Mspaint PixelArt, and the Oekaki), the highest is I can't even remeber ono; probably in the 20 -30+~ I always use so many cuz I might want to change a color half-way, so I'll I have to do is go to the layer an alter it. and most of the layers I use are effect layers. Like for the eyes I use, a Base color layer, a 1-2 layer for the highlight, 1-2 layer for the shadow, gradient layer + any other effect layer (like the stars in the second girls eyes). :p If I removed all the effect layers I would have a extremely low number, like 10-15 (Lineart,Eyes, Hair, Clothes, Skin, misc.+ Shadows, Highlights.)
So on a image of a girl in a dress with only a headband in her hair, I would use about 12 layer. Also that and I use the folders because I tend to get my layers mixed up alot when there not seperated and named.
Tl;DR: I use alot of layers~ Lol.
Where'd you get that pallete box? It would sure help me instead of using "that wheel" in OC.
I really like this concept, not very techno-y like most Utau's I've seen. 
The Pallette Box came with PS7, I barely use it except for grabbing base colors, etc. then altering them to my wishes.
:p I didn't want her to "look like a Utau" because all Utau have there designs based of vocaloids (no as in copied but you know what I mean I hope)
