this is super cute! what program did you use? 0:

MS_Paint >_<

1st i draw the image with mechanical pencil
then i ink it (& erase the original line work)
Next i use MS_Paint to 'acquire' image via scanner ( monochrom .BMP )

the monochrom .BMP format only has 2 colors black and white. because it eliminates
grey pixels you can easily manage your original line work.

the next step is a tedious proceess you scan in the image @ 600 dpi but then scale it down to about 33% of the original size depending on the size of the image. but here is where it gets painful, you have to do a process i call "de-burring" where you remove stray pixels, shave off jagged pixels,
fill in bad spots/missing pixels and adjust any linework or errors in the original drawing.

for integrity purposes i rarely do a lot of line editing.

then i change the format to 24-Bit .BMP

Lastly the fun part!! COLORING! i use my own custom pallete, i coral off sections of
open space and use the fill tool to cover those areas quickly.

and i save a copy as .PNG which is this file.

This one is my fave! <3

Thanks~!! This one was my Favorite of the set Also!
