Pool Party Sona Concept Art Feedback

I have seen a lot of Pool Party Sona that just wear bikini and call it done. Because of that, I decided to design a concept that is more related to music theme for her. I have her wear hula dancer's grass skirt because Riot never gave her legs model, I don't think they would use DJ Sona legs to create another skin, so the skirt is pretty much require. I know the hands and drums look terrible, critique on my poor technique is always welcome. Sorry in advance if I offend anyone, I have little knowledge on Hawaiian culture, I only draw what I have seen. This is me o.o

Also, I could not come up with any particle effect other than some flower theme. If anyone have a good idea, please share it with everyone ^.^ Another thing, I can't decide if I want blonde or blue. I find blonde to look better since the it settle in very well with the rest of the color scheme, but it doesn't look like the original Sona. On the other hand, blue, which still look fine but not as great, look more recognizable as Sona.
