I think the sparkles are great! The blurry ones are a bit confusing because they seem like they should be really close to the viewer, but they also happen to overlap the back of the broom- so I wonder if they meant to be coming out of the back of the broom. You could remove them, move them, OR, add MORE of them- which gave me the idea that perhaps the bottom stream of sparkles could come closer to the viewer? Like we're in the stream, looking in?
And thinking about the sparkles- I think this is an opportunity for really dramatic lighting! The sparkles could be providing really intense and random light, giving you the opportunity to add small but bright highlights all over. I'd take inspiration from your Red Riding Hood or Redwoods piece, that have intensely bright/dark lighting.
Have you played with tilting the composition at all? The perfect horizontal feels very stable and 'at rest', but with the action in the scene, I think it would benefit from a more dynamic diagonal to give it energy.
The light purple behind them reads as very opaque, but I get the sense that this should be a very airy scene. I'm not sure what to suggest as a solution, but just wanted to call attention to it.
Oh! And I just noticed the frog just now. Oh what a cute little frog! Hmm, can you make the frog more prominent somehow? Like nestled in the boy's scarf and holding onto his hair? Or the boy's arm is outstretched and it's holding onto his cuff? I get why story-wise you might have the frog tucked in more, but composition-wise I'm missing the frog. You could also just brighten its green, or change the girl's green sweater so that it's not green and the frog is the only green, and then pops more. The comedian in me thinks it would be funny if the frog was at the very front of the broomstick, arms holding on, legs flying back, haha- but story-wise, maybe you want to show the boy being protective. 
It's cool to see you revisiting this one! I think it has a lot of great elements.
