hey!! what angel said is a good way to get back into art while also learning more techniques. i rmbr watching a video yesterday that talked abt how observing ppl's art style n studying is one of the most important pieces to learning art.
what id say too is just use references with art if you get frusturated with your art. i feel as if anatomy, shading, coloring, n perspective, etc can be a hard thing for artists but using references is a good way to learn while also being able to draw what you want exactly. you can either use ref photos online, or find websites that have a 3d model that you can move n shape n morph into something you want to draw exactly. or you can also buy little art mannequin figures that you can interact with irl n morph it into a specific pose, angle, etc.
anyway keep at it n good luck !! :-)
