Mermaids and Jellyfishes III: little progress

I haven't been progressing much due to procrastination. (I'm sorry!) But since it's been long since my last update, I figured I'd at least post what little stuff I've done.

Tail body and one fin done. Figured I'd finish the background first
before working on the other ones.

Starting to work on jellyfishes. Also added some warmth to her skin.

Right now most of the stuff I need to do requires transparency. I think  mask layering can help me with that. If you have any suggestions, let me know at the comments!
