Hey thanks so much! A tip I use when starting my pieces is to work in grayscale first. This shows me where I need more contrast to have a more balanced piece. Also, when working in color, I try to pick colors that pair well together, like red and green (opposites on the color wheel) but there are a lot of options with color, so experiment with color groups that you prefer, then lighten and darken them based on how well they read when next to each other. I hope that helps!
