I'm going to bite this time because frankly, I like your variation in line thickness a lot, if anything your digital linework is pretty rad.
>hi how can I make my drawing less boring? Pic related is a /v/ drawthread request I made a while ago, a similar concept, office lady, but it's byleth for some reason. The nice thing about static poses (like in the second and third pictures) is that they are easy to construct and can show off tits and ass (and i suppose cocks if that's your thing) and the japanese and most patreon artists seem to love them because they give massive real estate to all aspects of the body at once. But consider this, if you're giving everything emphasis, then you're leaving no focal points, less aspects of realism (we rarely if ever see all parts of the body unobscured, even now you probably at best only see your hands and perhaps a reflection) people spend most of their time looking at their hands or other people.
http://www.alexhays.com/loomis/Andrew%20Loomis%20-%20Creative.Illustration.pdf is the only book by loomis that doesn't feel outdated imo or is generally easy to nitpick because it tackles less formal rules about the figure and more about just, literally, being more creative as an illustrator. Read page 34 (in the pdf) about informal subdivision, pg200 on colors, those are the two most important concepts imo.
Lastly, Vilppu once said in a video I watched "Take the pose yourself, feel the tension and where the weight falls and convey that in your drawing"
