Very good
The show Steve Universe has always been one to enjoy, a relaxing funny cartoon. You captured that relaxed feeling here with the way the female Garnet has her facial expression and hair flow. The colors are spot on for this background and the bubbles around her are pretty neat but id make them a bit more consistent in flow and size as they seem a bit rushed here and there, And so my ending note with this piece is that it has some good value to it, it has some artistice style to it, and i pretty much enjoyed what you have presented here, hope that you make many more great stuff as this one, it was top notch in my book. So try and get some more Extended efforts in this one.
~~THINGS TO IMPROVE ON~~
More details in the purple bubbles to add some consistentcy maybe make them less blurry
