this is going to be very brief so don't expect alot out of this
1.inital sketch...just any paper...any pencil...sometimes i outline it so i can see easier.
2.i do any BG lineart first, in this case i opened up a new file and rotated the image around to make it easier for myself.
3.oh yeah, i use the pen tool for my lineart~ i'm not gonna explain how to use it...you'll ifgure it out.
4.i make all my decorative lines on a new layer, my main lines are at 4px while my decorative ones are at ether 2-3px.
5.i use the pen tool to make a fill when i do face lines, then i erase the bits i don't want. like the inside of the eyes.
6.cause i'm lazy i use the selection tool to fill my stuff...i make a group for each colour or section(hair, skin, orange, black).
7.i use the pen tool like crazy when shading and highlighting...when i make an area with the pen tool i turn it into a selection and ether fill it flat or i use the gradient tool.
8.for lineart colouring i just lock the transparency and draw in the colour.
9.i colour the BG the same as everything else. if there's special lighting in the picture then i'll make a little overlayed light on it.
10.it varies for each picture...
if you've actually gone this far down...check out this trippy animation i made of the progress~[link]
