Zinnnia sketches in gouache

These are sketches I managed to do today while being very busy at the office. I couldn't resist using my new gouache and painting these zinnias. I picked these from my garden and brought them to work where I can look at them all day. Of course, the only problem with that is I cannot resist the urge to paint them. They are absolutely luscious. All the glorious colors.
I've mixed the gouache colors with transparent watercolor and there is also Inktense pencils and regular Prismacolors in there.
