Here are few professional illustration and graphic design works I have done ( client + personal projects ). My work usually has a bit of a raw touch to it and I love to work boldly with colors and lines.
Nowadays I work mostly with Adobe Photoshop + Illustrator to digitally create my work. When I draw by hand, I mostly use traditional pencil and colored pens, markers or pastel chalks / charcoal. Water color and other painting tools I have yet to figure out properly.
My personal style is very flexible: I can draw with only few lines or even pretty realistically, and everything in between. Let me know if you would like to see some specific work samples and I can do some quick sketches to show you how my style could work for your project!
