I noticed the colours were too drowned out in the last piece (pun unintended), so I tried using darker colours here and there to emphasize the brighter colours more and prevent them from blending in too well and losing their shape. Aside from that, I'm also trying to approach lineless art, and learn lighting. Watching how others light their drawings makes me realize that I've still got a long way to go.
Watching a video on the regards of colour harmony makes me realize I would also have to learn to use colours of varying saturation, value, and hue as well, and thinking that I at least now know where to improve and experiment at makes drawing an exciting thing to think about again!
