Life drawing in the style of Franz Kline and Oskar Schlemmer

Using my skills from working with Schlemmer I included the lines in my drawings to keep the proportion of the body alined and formed correctly. I feel I still need to practice on using the lines correctly as I feel that her body is still very out of proportion in my opinion. Although after looking into Franz Kline's work I discovered that he uses bright colours. This gave me an idea to create my drawing in the style of Franz's work, using charcoal I filled in areas that were dark (blues/purples) or really light (yellows/whites) to add more of a vibrant look to my drawing. However I did find drawing the model in this position very hard as she was sat down, this meant that  areas of her body were narrow and creased up such as her legs and her chest.

Now in this sketch I just worked with Schlemmer and tried to focus on the lines. I feel with this drawing I did well on the proportion of her legs and how they cross over slightly. Although, it still needs improvement on the top half of her body and her neck is slightly too long and her chin needs to be formed more as well as her chest.
