Hi. Thanks I'm glad you liked the drawing, if I also used that application, and it's pretty good too, the sketchbook is better in the simulation of the graphite pencil brushes, pastels, charcoal, you get a more realistic finish, the fading system feels better, much softer, but it doesn't have much variety of textures, the engraving system of the video drawing process, is usually unstable, and there are errors where you stop recording, a serious error when recording the process. The procreate, has much more variety of brushes, the interface is more intuitive, has more interesting tools, the video engraving is failsafe, accepts Photoshop brushes, and export the drawing in that Photoshop format, with layers and everything. In short, the procreate is more professional and with many more possibilities of development.
I hope it helps you :)
Helps a lot actually--thank you!
