I painted these for my color theory class with watercolor. The assignment consisted of painting an indoor window looking out after 5:30pm. The point was to capture the reflection of the interior over the window overlooking a scenery during twilight. I found this challenging and I did get frustrated but one must keep going and practice.
I prefer the first painting above; the second one I was experimenting with a themed color of purple, I don't think I succeeded. It looks sloppy, but I'm posting it anyway. I'm still mostly clueless about color theory... A part of mastering it is a hyper-awareness to seeing-- a skill that requires immense practice and work!
