Oh, haha, I'm so glad you appreciated the advice! And yeah, oil paints and doll faceups? That's a no-go. It can't even be craft store acrylics, they'll just flake off of the faceup in pieces. It has to be the expensive acrylics used for modeling, try Testors, or Liquitex.
As for the bruising, that's why I suggested pastels (forgot to mention CHALK pastels though, no oil base
), because I do special effects makeup on my own face as well (when I used to go out on Halloween people would think I worked at one of the local big budget haunted houses
) and I can achieve beautiful bruising effects with a simple child's facepaint kit, but with dolls and their non-forgiving surfaces there's no way to "blend", which is what gave the faceup the jagged edges around the bruising. Ground up pastels on a q-tip (I'm sure there are a million tutorials that explain the process better than I do) are perfect for creating that blooming bruise effect.
But still, knowing you used OIL PAINTS and it came out that way....wow!!!! I would LOVE to see the kind of faceups you could do when your materials aren't fighting against you. Congratulations on wrangling those paints to do what you wanted!!
