I really struggled with this drawing. I tried a Monarch (Minnesota's state butterfly) in two different wing positions. Both of those attempts are in the recycling bin. The wing markings were much too intense for me. I also had trouble with the idea of doing one in black and white... except for some very gorgeous black and white ones that I did find on the internet. I liked the blue on this one (I think it's actually called a Karner BlueButterfly that used to be common in Ohio). I have some new colored pencils that I thought I would try for this one. I used a Micron pen for the initial drawing and then did the colored pencil.
It actually looks a little better on the screen than it does in my sketchbook.
