Is this a digital drawing? If yes then in which software I can make this?
Apparently it is a digital painting: http://www.cuded.com/2015/08/sweet-digital-art-by-destinyblue/
You can ask the artist which program she uses.
- Photoshop seems to be the preferred program by digital artists (from what I've read throughout the internet).
- From the little experience I have in digital art, I think you can achieve such effects by any decent drawing app, too (Autodesk ScetchBook, Medibang Paint, etc).
- You can also use other non-digital media to achieve such or similar effects, such as gouache/tempera, oil paint, (probably) acrylic (I've never painted with acrylic, so I can't tell for sure), etc.
According to her FAQ and detailed description of her working method, she does indeed use Photoshop CS6 and "a little" Paint Tool SAI; she uses a Wacom Intuos Pro 5 for digitizing her drawings.
For your information, there are a number of additional widely used software for painting:
- Sketchbook Pro (Win, Mac, industry standard)
- Procreate (iOS great brush dynamics)
- Krita (free, open source, Win, Linux, Mac)
- Blender (paint and sculpt at the same time)
You want to be sure that the software you are using is calibrated to your drawing tablet, and that both tablet and software support things like pressure and tilt.
Personally I use an iPad Pro with Pencil, but you can also use an inexpensive Wacom Bamboo drawing tablet with a computer.
