Well done! I've seen a lot worse - and it's certainly good enough for publication. Your chosen view of the prone victim involving foreshortening is one of the hardest poses to draw well, and I wonder a bit about the legs. If one draws exactly what they see of a model posed in this position, the result comes out looking lumpy and a bit shapeless. The skill lies in exaggerating the perspective just enough to make the drawing look correct. (Too much, and they'll seem 10 feet tall). When Salvador Dali's detractors claimed that he couldn't draw, he deliberately chose a foreshortened figure for the subject of his 'Christ on the Cross'. The result silenced his critics!
I was late in coming across two books by Burne Hogarth, (he who drew the Tarzan comic strips, and also taught at New York School of Art). 'Dynamic Figure Drawing' and 'Dynamic Anatomy' made a big difference to my approach to figure drawing. I'd recommend them to anyone, be they student or graduate. Good Luck!
