Extended Practice: Sketching

I have tried making a few sketches while listening to my picked song and see if I could come up with some concept work. Here a couple of sketches I have done in my sketchbook studying the anatomy, trying to stylise it and try a couple of different angles and positions, no reference was used for these sketches:

The next thing I will do now is take some of these sketches and try to digitalise them, see if I could come up with any concept work from this.
