Sunflower study

I wanted to try something in my shading in colored pieces. I tried using as little black and white as possible and portraying the different shades mainly by a difference in hue, which I mean to do generally but sometimes fail. I think I got a decent result.
Gouache on paper. Referenced from one of my photos. Cellphone picture because it actually looks more like the actual painting than what my scanner gave me. Go figure.
