After several weeks I bring you... this!
My current progress on the shading layers of Skull's frames:
It's now more near to be completed, a lot of cleaning up went and will left to do.
For now I will do a check list of things that I need to work on:
-Finishing the base layer by completing her braids.
-Shading under her skirt, neck, hand, sagan and sword.
-lighting effects on her head, legs, shoulders, star and sword.
-Reflection effect on the sword.
-A lot of cleaning up.
-If you notice something odd please tell me, that would help a lot.
And this is how it looks with a Multiply filter over the color layers.. I don't know how the game interprets palettes but this might do just for now.
Other things that are left to do:
-Fix her quick blinking.
-Start making the palette areas for each frame.
-I...I'm out of ideas.
