Jaik: Thanks! I usually feel insecure and a bit inferior for doing observational illustration from life because people probably consider it unimaginative and boring compared to creative concept art paintings.

Yellow was not a good idea. Don't include next time.
The light in a watercolor painting comes from the white of the paper. It is harder to paint the light back in once the white of the paper has been painted over several times.
The light in an oil painting isn't dependent on the white of the canvas. In fact, when the white of the canvas is visible through thin layers of oil paint, it has high risk of looking not brightness, but bad planning. However there were paintings in museums that the white of the canvas was used through thin layers of oil paint to indicate reflective light in tall grass that were not directly in sun light.
Painting on a computer screen has the light literally coming from the "canvas", so in that regard it's similar to watercolor. But painting digitally still feel more akin to oil paint's opaque paint. Thin layers of not-100%-Opacity digital layer behaves differently than thin layers of oil paint, but I don't know why. I can only assume physical light interact with and bounces more unpredictably with the chemical and varied sizes of pigment particles in paint layers, than digital.
