This reminds me of when I was a kid and I'd be given something to color in art class and it would always be something really complex and interesting looking, and I felt like I was accomplishing something when filling it in.
This... The lineart for this, would make SUCH a good page in a coloring book, or on one of those posters you color with markers but its all fuzzy (no idea what those are called).
At first, I was like "Oh look, a fancy bit of artwork with Pinkie Pie in the center." Then I was like "Wait a second, is that a stained glass window-esque picture?" THEN I was like" It reminds me of Kingdom Hearts...." Then I fangasmed.
Well, usually for the previous efforts, they took me around 2 weeks but since my PC monitor has somewhat been screwed up by some dust (I think) as well as the gradual lack of ideas, that has been increased to more than one month! Anyway, thanks for asking!
