Each pict as a reason :
-Boring painter : just a test, no line or idea, that is the only pict without line.
-Selfing octopus + the other (not a mask of death, just the flash burn his face, it's a joke) : draw it for a competition, a SF comic book ask a pict with a selfie.
-The knight : i draw Link because i like Zelda and a friend ask to me to draw it to print and buy it, same reason for the Jawa and SW
-Infinite page : i don't understand what you talking about when you say "but does it keep every pixel in it" (i'm french, sorry for my english) ?
To be honnest : what you are talking about ? XD I'm drawing, that's all, for me or orders, that's my work, nothing else.
