I'm drawing every day and everywhere many small birds... I began with the simple forms... and each bird drawn I insert the freedom scribbles on its form... This work I made for Cristine, my niece, they are imagery studies for my story about The Boy That Would Be a Fish.
These sketches were made with gimp, I've used a brush that I thought initially for crayon emulation, but I could see is possible emulates others techniques, as watercolor, it depends mainly of the blending mode that we apply on brush. In this case I've used the multiply.
