Clip Studio Paint is my savior. It offers a variety of brushes, as well as 3D objects for easier scene settings. Other than that, I prefer the UI better than Photoshop since the bars are less clustered. And it automatically comes in dark mode.
Sketchfab is another website that I use since I can choose a specific angle to have as a reference for any kind of object.
I started using Krita since it was free software but I switched to clip studio paint since it has more functions that I can use such as using other artist’s shared brushes and tools.
I start my journey with photoshop and until now too. Becasue it’s really versatile for me to draw characters and painting backgrounds. I also use clip studio paint now because of the 3D figure feature which is really helpful and some brushes are unique. Sometimes I also use blender to make draft for background.
