Spectrum Art

the transform tool lets you select a section of a layer, and move it somewhere else. it only exists in digital art softwares.

I have a question about art. I'm new to it. I'm overwhelmed by all the things to learn and how there's no path to follow. I'm stressed out about it. Everything seems difficult. What do I learn?
also its genuinely not really supposed to be like hes got it behind his back. its supposed to be more like he's holding it sort of perpendicular to himself.
