last set of polar bears

the last 60 polar bears have definitely proven to be the most challenging. I think the reason I'm having a harder time with them is because I cant simply do them in a sketchbook, and most of them, I cant even do with a pen or pencil. Sketching by hand is most likely the most efficient way for me to get things done. But by being pushed to use some other styles, I think will really help me to create some images I never would have otherwise.
