>>3608646>>3608646what kind of technique? That looks like that "standard pixiv-artist painterly look". So it's basicly simple digital painting.. So there is no way to PAINT like this with PENCILS. wtf. It's a totally different medium. (I'm not even sure if this a joke or not)
It is possible to emulate traditional media with digital, but impossible to recreate the default perfect round brush using traditional tools.
Here is how you get paint like this:
Get a graphic tablet
Get Clip Studio Paint or SAI
Learn how to do digital painting by doing studies (copies) of real life and other artists works. Yes, your first portrait will take probably 8h to finish and you will color pick the colors from the reference your're copying, but that's how it starts. Painting is totally different from drawing, btw. It's like a different world. In Painting it's all about edgework. No Lines.
The artist of this piece is not even using a special brush either. It's just the default brush.
with variable hardness, size and a normal blending brush. That's all. So it's not the brush in this case.
It's the understanding of how light in real life works and interacts with color. You can watch videos of oil painting tutorials for that for example.
Add a paper texture on top of everything with Overlay or Soft Light layer blending mode, do some color correction, done.
And you definitely don't need years to get to this level. You don't even need to "paint every day" or art school. I tought myself everything via Youtube.
