Just now I am practising sketches of humans in various fighting poses. I use www.posemaniacs.com as a resource. I plan to use some of these sketches later in one or two of my illustrated cat story. I am also practising colouring with the lasso tool.
I confined myself to 35 minutes for sketching and colouring, and I know that the shadows and highlights are not complete, and the drawing lacks accuracy. But I wanted to get the gesture, the pose.
