This started as a little study of drawing in grayscale first, then on a new layer add the color with the color layer set to "multiply" so that It could blend better with the sketch. Then I thought of putting the different versions together to form a picture, and then put it a museum type of background, though only in lines.
nice idea. maybe you can expand this imaginary 'gallery' by doing one or two more of these with other characters. i dont know if you do know how, but as a suggestion, in a combination with a sliding camera? would be nice to see the other picture frames filled ^^
Looks great.
Also, Pinkamena + Surprisamina fusion... Everybody run for your life!!
Any thoughts behind the botom right one though? The others I can understand the choice of colour for, but the last one escapes me.
I don't know, thats what I think of.
Still, she came out great.
