Illustration sketchbook #1 - Part 1/2

Here's the first half of an illustration sketchbook i recently finished. Tools used are primarily markers, brush pens and some color pencils, with the occasional acrylic touches. It's mostly driven by experimentation and learning how to use the media batter as well as trying to learn more about form language and color. Having the limitation of a restricted palette made everything more fun and challenging, even though i did end up buying more marker shades :D.
