With the crew, I started painting the ammunition. Over the white over purple zenithal, I applied 4 washes to get some variation in color.
Once these were dry, I applied a thinned down wash of black ink.
Finally, I applied a drybrush of a very pale green.
These rocks make me quite proud, I didn't use a single grey in painting them

There are no (purely) grey rocks in nature
For the crew, I used a technique the first time, I learnt of from
Ninjon. He developed this technique over some time now and it features in many of his recent videos. The idea is, you paint an area in a colour transition of two colours, wetblending these where they meet. Then you paint your main colour of that area over this basecoat, letting it show through, and you quickly get a complex mix of colours without long blendind times. I decided to use this technique for all the greenskins in this project.
In the following three pictures, on the left you see the basecoated models, with the two colour blends, on the right the result after applying one colour on top. The metallics I stippled on, to let the basecoat shine through. The other areas I painted thin paint over the basecoat in two to three steps, in some areas with an additional second highlight step by adding zinc white.
Overall, I can still improve on this technique, but I like the effect a lot, and it is indeed a rather quick method.
I still have to apply oil washes, but so far, the majority of painting is done.
