I've never drawn a jellyfish before so this has been pretty challenging. And after looking at it for so long it looks fine to me but I know it needs plenty of work. I've looked at a ton of reference pics and the thing is that they are pretty much see through and there isn't any form to them. This is going to be for a tattoo so it'll be solid colors with not a lot of see through aspects, if that makes any sense. Open to any and all critiques and feedback. Thanks.
cnotes, welcome aboard! I really like your idea. Depending on the size of the tatoo, you'll have to be careful with adding too much detail to the hanging membrane. As for the fill-in, it really depends on the style of jellyfish you're going for. I would suggest adding strong coloring/shading to the perimeter of the head and adding blur for the transparent areas. Somewhat seen in this pic:
