WIP2 for Jojodrums

I've been taking ages on this picture (it's by far the most labour-intensive piece I've ever done), so I thought it deserved its own progess shot.

This is my first ever time using acrylics properly on canvas, so the experience has been a STEEP learning curve. For this I'd sincerely like to thank =jojodrums who asked me to do the picture, as if it wasn't requested I'd probably have stuck to mediums that I'm more familiar with.

It's been painted over so many times that I can't count - but I think I'm happy with the progress. Any tips / information on how to get the most out of acrylics would be appreciated, or if you can see anything wrong with the pic so far, or (this applies to jojodrums in particular) is there anything particular you want me to add/change.
