for actual drawing lol; -if you aren't confident with head shapes, use circles to help guide and practice drawing the head you want -for bodies, break up the body into sections(as the drawing to the left shows), then sketch over and if you still have difficulty, then practice anatomy and go from there -for expressions, use references and ideas, try not to use the same face a lot(i have a bad case of same faces) -don't be afraid to leave drawing a little messy, i sometimes use the sketch as the lineart! it liven ups the art and keeps it from being stiff -use simple shading, flat color is fine too, but you don't have to like cell shade or something, simplicity is very pretty if well done! -don't be afraid to experiment! try poses and dynamic faces! it also is a nice way to help art block and boredom. the best advice i have is to practice and have fun with your art. nobody's art is perfect, so don't worry about small things. have fun drawing!
