When I started painting, the first material I used was colored pencils.
I prefer colored pencils when sketching or designing characters. It is a very enjoyable material both to play with colors and because of its practicality. Here are some portraits.
Creating botanical background is one of my signatures. After all, there were hundreds of different kinds of plants and colorful flowers in the house I grew up. Yes, my childhood was spent in a house with a huge garden =)
I take small sketchbooks wherever I go, so I prefer this size a lot.
