Hahaha - ich will den Scheiß jetzt nicht verteidigen aber so schlecht isser auch wieder nicht.
Photoshop is no good to use for painting out of the box. One need some special brushes for good smudging performance i.e. (I am still searching where I got mine from. 100x times faster than normal shit)
But there wouldn't be so many good Photoshop paintings, if painting would be like in your example, zero.
It's a Photo retouch tool which needs to be carefully learned to paint in.
Once you got this, you are almost not limited.....well with brush sizes under 100 pixels
I often regret not to carefully learned how to paint in photoshop, specially when it comes to photobashing an concepts in minutes.
But mostly just for a very short moment.
For Android or IOS I can recommend Infinite Painter.
Almost all tools one artist need in one package, a unbelievable quick developer and nice blending.
Anyway, the quality of the tools......content aware fill....did you try the new options in PS?...f****!!!!
Kaleidoscopic, mandala symmetry, smoothing. Thanks to all the small developer, Adobe needs to move as well.
Painting is just a tiny part in this app.
