Advice Welcome

Please can I have your thoughts on this.

I ran a couple of sessions for my local art group and part of this was demonstrating my process. The artwork below was what happened by the end of the session. This is not quite my usual style, although it is definitely abstract mixed-media. It is the sort of work, where I would probably leave it a while and then work over it some more. However, not only do I have no idea where I would take it next, several people like it as it is.

My question is do you think it is finished and should remain as it is?
