The initial ideas of this drawing was on one of my Flipboard board. I found it similar to my fave zine maker/artist Brendan Monroe. The hand was super easy to make:
1. Trace your hand on paper, I used HB pencil and Maruman watercolor paper.
2. Choose your ink, could be done in colors or monochrome. I used Ecoline 700 with 000-size brush and Sakura Koi Coloring Brush Pen in Blue Green Light (XBR#28) and Peacock Green (XBR#426).
3. Then start to make various lines. Imagine this, the line goes straight, until it meets your hand. It starts to bulge, following the contour of your hand.
4. After finishing your piece, try with your other hand. Or simply flip it on photoshop (just like mine on picture).
Have a nice weekend!
