I know I've pissed and moaned about this before,
but it irritates me to no end that the Asian BJD aesthetic requires fanatical devotion to every single detail.
God forbid you use your acrylics, watercolor pencils and brush-applied matte varnish to create a schematic, suggestive faceup. Nope nope nope! You have to go through this nitpicky, time-consuming process of waiting for appropriate temperature and humidity, spraying everything with extra super special sealant imported from Japan, then letting it dry, then applying a few brush daubs of delicately shaved pastel, letting it dry, etc., etc., etc.
While you're at it, you should be doing the eyebrows individual hair by individual hair with an expensive, microscopic brush...same with lines in the lips.
Let's say you want to mod your BJD: thin the neck, let's say. You can't just scrape it down to size with an X-acto, plop the head on and call it a day. What were you thinking?!! You have to smooth your rough shaping down with a series of successively finer sandpapers until no one can tell that you've done any work on the doll. We do not accept jerry-rigged solutions constructed with sweat and hot glue. We demand perfection in all areas.
Oh yeah, and if you want to make a hybrid BJD of a body from one company and a head from another and jointed hands, say, from a third, we'll be watching to make sure that you follow the correct protocols. First you have to ask online about proportions and fit because we can't have your doll being aesthetically offensive. We'll let you know if your proposed hybrid looks good enough.
Just as important as the proportionality of your hybrid is the hallowed concept of resin matching. You need to find out the relative colors of your hybrid parts. If your desired parts don't match perfectly in tone, you have two options. First, you can choose other options that do provide a perfect match. Second, you can do body blushing, which is like a faceup for non-facial parts [see excruciating process above], so that no one can ever tell that the hybrid parts were originally different colors. We do not allow BJD hybrids with "paper white" heads, "fresh white" hands and "beauty white" bodies to exist without their colors being evened out. Too many shades of white make us implode.
Guess what? My faceups involve no super special Japanese spray sealant whatsoever and, instead, lots of watercolor pencils, Prismacolors, acrylics and improvised tools [Q-tips, X-acto blades, toothpicks] to direct the pigment. Sometimes I haven't even bothered to seal the heads before scribbling directly on the resin. And then... I don't even wait for paint to dry. I use -- wait for it! -- a hair dryer.
My mods avoid sandpaper. I prefer instead to do exactly as much hacking with a craft knife or saw as is necessary to make the mod functional. It doesn't have to look nice; it just has to work.
As for resin matching, I don't really care. I mean, once I put a WS Elfdoll Kathlen head on an NS Soom Uyoo body [=Absinthe], and the world didn't end! Later, I stuck some NS Dikadoll jointed hands on an Angelsdoll massive girl in "Volks compatible normal" [=Janvier Jett], and the planet remained on its axis! Shortly after that, I decided to stick a rose grey Iplehouse Luna head on a B&G Dolls grey body [=Lura eventually], and the sky did not fall!
It's mind-blowing, isn't it? It's almost like there's another aesthetic option besides that of the minutiae-obsessed, anal-retentive facsimile of reality.
