AfricanVoodoo's Sketchbook

[AfricanVoodoo]

Yo yo yo!

This is a WIP of a character (sketches of this character is seen in the last post), that I am trying to work on. But oh my lord can someone give me some tips on how to do line art effectively? Do I only need a simple circular round brush or do I need to go fancy? (Also, some crits on the picture itself because I certainly need it.)

I am a complete beginner to digital art, let alone Photoshop so I hope I can get a lot of mileage in the medium as the years go by. 

Thank you!!
