While fairly obvious (to me) that I'm mud mixing like crazy with my cheap paints and miscellaneous equipment, this painting didn't come out as bad as I thought it would. My palette knife work on the tree trunks doesn't look very much like the bark of an evergreen (more like wonky sycamores) and I had to apply a lot more foliage up top to cover up the sloppy smears from the thick paint and the smudging branches. But considering this is an imaginary scene with imaginary trees, I kind of like the odd result.
I had to improvise a bit on the background since I didn't have any liquid clear and my paints weren't fully transparent, but it did let me give a bit of a hint of a visible light source which was fun and added an interesting element not present in the original.
Despite most of them being obscured in the final product, I enjoyed painting the branches the most, and probably ended up painting way too many before I destroyed them trying to cover up some mistakes.
