The air drying clay I am using is contracting quite a bit when drying, here you see gaps between stem and base as well as between stem and top. Both were not there when I was done sculpting.
So I had to take another round and fill those gaps at the top at least, the ones to the base will be covered by sand anyways.
When all were done, I gave them a coat of Mod Podge, cheap acrylic black and alcohol (to get the mixture better flowing characteristics) and sealed the models.
The "leaves" are now pretty hard, but still thin, so I must pay attention to not exert too much pressure with my fingers, when handling the trees, otherwise the "leaves" will snap off.
Next came the airbrush, I first mixed Molotow Purple Violet about 4:20 with Molotow Vanilla Pastel as an underpainting for 3/4 of the height, leaving the top black. Then I came in with pure Vanilly Pastel over the whole stem, leaving the purplish tone slighty showing towards the bottom.
The top "hairs"/centers of the garlic was also sprayed Vanilla Pastel. The "leaves" got a white ink spray, trying to get them less covered going outwards.
Next up are some oils.
