my latest oil pastel experiment is this painting of three pine grosbeaks, referencing a CC0 photograph shared as part of an observation on inaturalist.
this one was created on illustration board, with a full under painting in watercolor first, which you can see in the third image. The illustration board texture has a wonderful grain and could be a very satisfying surface for oil pastel, but it tends to warp pretty dramatically when painted on with water-based media. you can see any image on the right how much it has bowed out while wet; what you can’t see is that it has an inverse warp in it once dried. clamping it down to draw on it released some but not all of it. unfortunately this means it’s just not a good solution for anything with a watercolor under painting.
inaturalist has been a really exciting thing for me to explore, and once I discovered that you can search observations by image license I got really excited. if you’re also looking for reference, especially of specific animals, it might be a great place to start.
