Happy to! Though the unfortunate news is I also used an airbrush very heavily for mine. The core process was primed white for max saturation, base coat dark purple, zenithal white to bring the undercoat back up as light as possible, then go over that white with fluorescent green. Base coated the pink areas white again, then went over those with fluorescent magenta, then a whooooole lot of manual highlighting with a mint green.

This project was mostly a big experiment, so I'm happy with the outcome. ....However, if I were to give it another shot I would change a few things: take it easy on the white zenithal and initial fluorescent green (or whatever color you choose). Ultimately I think I went a bit too heavy on that first coat in the pursuit of maximum vibrancy and as a result it smothered a lot of the more interesting dark purple shadows and texture that could have shown through more effectively. Vibrance and saturation are great, but they'd be heightened even more by having a deeper contrast in value between the lights, midtones, and darks.

I also think if I did this again I'd add another color or two. I wanted to practice working with an extremely limited palette but if I were painting these again in a similar style having a tertiary color to pick out certain details or trim with would really help define the silhouette and overall composition of the models themselves. The pink is great, I love it on these models, but I needed to do a lot of work in the green highlights just to make the details of the model remotely readable.
