Since someone ask me how I do my digimon, I decided to make a primary tutorial before that to show how I do lineart for both my Digimon and Pokemon submissions.

I find since I lack a tablet that hand done lineart is the fastest to do and looks good when shrunk especially.

The only time I use pen tool lineart is if:
a) I want my image to look extremely professional on a large format
b)I want things to look really smooth

Hopefully you get what I'm talking about most of the time here, if not feel free to ask questions.

Btw, the digimon feature is called Duckmon, its an fan design so please don't used it without permission
