I also have a portrait long study, which I didn't scan properly, and I will add later. The first drawing here is the final body long study that I do at The Drawing Academy, which I cannot claim entirely mine, because I got a lot of help from my teacher. I think it took around 9 hours to finish.
The second is a 3-hour unfinished study . The next are 5 to 10 mins croquis, and the last one is an unfinished study also.
I started a digital self-portrait painting as a vampire. I'm mentioning this so that I will be more motivated to finish it eventually!
