I finished this in a short period (about 4-5 days) which is my personal record

Then I had to go on Xtreme Martial arts seminar and I knew that I would be totaly shaken..

It's all done with wooden pencils, white marks with white acrylic paint (Tamiya > plastic models paint

)
I've kinda messed colouring the rims but that doesn't matter that much
