/ic/ - Artwork/Critique

Hello everyone.
I just picked up my loong lost art of drawing (see pic for my progress today). I haven't been drawing since my early teens.

I'm currently using a sharpie and calc. block along with a black ink sharpie to fill the lines.

What i want to learn is to draw people with the possibility to scan and keep going in photoshop, for this i assume i need other material, like special red/blue (?) pencils together with different types of ink, i assume.

My goal is basically to broaden my ability to make proper art out of my scetches. If you help me out i might actually post my first scetches from today, that im not proud of at all :D
