Looking really cool! Love the thematic of this and that face drain! I don't know where in the process you are but just in case there's a few things that come to mind for me: timing variation, color variation and shape variation with sparks (maybe try some very subtle soft nova/smoke type energy to accent some of the sparks). With the timing you do have pieces that give it a bit of variety like the pop in, the face drain and the fire, but the supporting elements like sparks don't reflect that energy as well as it could. Colors are all the same orange additive, perhaps some hue and value shifts to break it up where appropriate (subtle shifts go a long way imo). Looking forward to seeing more of this! It's so close!!
