I finished my first layer of OP. I always starting in with OP sticks and silicon shapers, so far I don't have all grown covered. Sometimes I go right away with second layer - same method - sticks and shapers.
After I'm done with that, I'm switching to solvent and brushes and here it becomes more oil painting, then anything else.. This is a more delicate stage and takes longer time, because often I have to wait till solvent will almost dry, before I can continue.
This is exactly a part what I'm up to with this work right now- brush and solvent. Not finished yet, but getting there.
