A short list of content-rich links that I've compiled for the good of you. If you're serious about being successful in art, it's essential to do independent study. From personal observation, I've noticed that high school art classes are viewed as a place for "easy A's". This mentality will drag down student engagement as a whole. To compensate, teachers are often forced to lower expectations for their classes and reduce the thoroughness of their teachings. Take it upon yourself to be responsible for your education. Study the fundamentals from reliable sources and work yourself up through good technique. In addition to using the links below, consider consulting your teacher to critique your work outside of class. www.conceptart.org/
<--- A resource for critique, textbooks and tutorials. This is a website populated by professionals so be mindful of how you conduct yourself on the forums. www.huevaluechroma.com/
<--- A thorough and modern explanation of color theory. purplekecleon.deviantart.com/a…
<--- A more digestible approach to color theory. It might be useful to start here before tackling the link above. www.posemaniacs.com/
<--- SFW figure drawing fodder. The hand poses are especially useful since they rotate on a 3d plane- just be aware that a nsfw torso model will appear first when you open the hand collection. In terms of the whole figures, they are not completely accurate and you will probably be better off using the source below. www.quickposes.com/
--- SFW and NSFW source for figure drawing. It offers a large library of photo references plus guidelines and tips for improving your figure drawing technique. marmonaa.deviantart.com/art/Em…
<--- Expression Cheat Sheettracyjb.deviantart.com/gallery…
<--- Humorous and helpful tutorials by Tracy J Butler (The Lackadaisy cat lady)
The links above are my typical go-to's for reference, as I remember others I will add them.
In addition to the links, consider keeping a folder of inspiring and useful art/references on your laptop. Add to it as you browse deviantart. This is good for when you need to check an anatomy detail on the fly. It will also help you locate what techniques characteristics you want to incorporate into your own art.
I understand that I am totally amateurish at what I do so you might be skeptical at using me as a source. Follow the links and decide for yourself. I genuinely believe this will be useful to others.
