Another picture that won't be finished, but I like enough to submit.

I had a really neat idea, but I just couldn't transfer it to paper/tablet. :/ That, and Sonata's mouth shape doesn't exactly make a pursed-lip expression very easily.
The shading prolly needs to be more dynamic, and I had intended to add several more smaller fireworks in different colors around the large one, but I got frustrated with the picture in general before that could happen.
I want to try this again someday, but I need to work on Sonata's expressions before then.

Tips would be wonderful!
