Practice is everything. The more you draw sketches more progress you get. When I graduated from the art academy, we went to a museum and copy famous artists to understand their lines, shapes, and composition. Later you will understand how to progress and build your style. You can find some youtube videos or courses, but I suggest the SketchAR app where you can try to draw from scratch and your artistic skills... Source: almost 3 years ago

Thanks for the help everyone. After following some of the concepts all of you mentioned, I came across another tool today you might find interesting — Kaedim (https://kaedim3d.com/). It did a pretty good job of creating a 3d model of my pic. I’m also playing with polycam, but havne’t finished yet. Source: about 1 year ago
