Just came across this one today after joining DA recently, I am humbled at the quality of your beautiful drawing and can only dream of producing work this good in the future. Fantastic hair and tone throughout, keep up the great work!
Hmmm, that's what I did with this, but it wasn't that easy, had to use the carbon pencils first (I used them to create the dark bits) and then used normal graphite on top of the carbon. If you then decide you want to use more carbon it comes a bit tricky because the carbon will not stick on top of the graphite. Cheers
