I just realised I don't know how to draw shoulders!
If I'm doing the character art for this game I really ought to practice pretty quickly. Which is what I did today:
I used some reference and a little reading ( http://www.howtodrawmanga.com/pages/tutorial_bodies ) to get the concept, now I'll need to repeat this a bit to hone it in. Which is good as I need to experiment with my character design too, so I can do both at the same time.
I also had a quick play with the mosaic filter in photoshop elements for backgrounds:

This filter looks like it will fit in well with my planned aesthetic.
