I love the coloring on this piece; the warmer colors for the one walking (combined with their simultaneously stoic yet worried expression, which is also subtly fantastic) juxtaposed with the cooler colors for the fallen one very much portrays a sense of dependency between the two characters. Additionally, the background is spectacular; I always love seeing your abstract renditions of landscapes because they evoke a loose, almost watercolor feel while being very structured.
If I did have one criticism, it would be that the posing isn’t particularly strong. I don’t think it’s immediately obvious how the walking character is supporting the fallen one.
Other than that, great work on this piece!
