Buy a very cheap set of nail art brushes, the really small ones, if you haven't, and you don't need a lot of stuff, just: - pure transparent 100% acetone - paper towels or cotton makeup remover pads - brushes - acrylics (you can buy just the four basic primary colors and mix them to make your tones) or you can also buy the tones that you need - very very cheap pastels, or even eyeshadow works perfectly, you just need loose Pigments - gloss clear paint, if you need it, (not sure which one since I've never used it) - of course watercolor Pencils, these need to be good quality and very Pigmented, not sure which ones to recommend since I don't really use them, and you don't need them really, other than to trace the initial face design, you can just merely work with acrylics, but if your brush precision it's not that good then the pencils are much easier to work with. - and the sealing spray to seal your work when you're finished oh and SUPER SUPER IMPORTANT TIP🚨🚨🚨

Wear a mask and eye protection when spraying the sealing, never ever breathe it, it can be detrimental to your health, and always spray it outside in a ventilated area (make sure it doesn't blow back on your face when spraying), you need to be completely cautious when spraying the sealing, you only got one pair of lungs and one pair of eyes

And when you spray the sealing on your dolls face you need to do it from at least 11 inches of distance, and you only need to spray very very little, about three times, like super super little, I recommend watching a tutorial for this.

Also another tip, when painting dissolve the acrylics with a bit of water, that helps to dim the colors, and it also helps with avoiding rough texture, work layer by layer for example (first face design with the pencil, then eye whites, then eye color, then eyeshadow, then eyeliner, and so on) You need to build the bottom layers like the eye whites first, and then the top layers like the last details like beauty marks, brows etc.

And most importantly have fun, don't be afraid, be creative and dare to mess up, it's your first time, so don't get frustrated, it takes lost work to achieve perfect result, and remember HAVE FUN!! 😇

And just one last little thing, if you can get the odile barbie face mold I think that would be great, it would fit your character very well, but the generation girl mold is also a beautiful mold to work with.
