I think my background is almost done, I just need some critique.

It's okay, but feels a bit bare-boned. It's as if she wrote it herself in a hurry (judging by the tone and the use of "meanie heads" and so on). While the tone of it isn't the important part, what I would like is a bit more detail here and there. I can't really point at anything specific, but it feels a little short. For example: Why didn't she want to become a "government weapon" as she say it? And how did she discover that she was lesbian? 

Then there are also a few concerns of mine: Her size. Yes, she's a Mer-shark, or mermaid with shark characteristics, but being almost 5 metres long (or 16 feet in imperial units) is a bit much. Could you tone it down a bit to, say, 3-3,5 metres (10-12 feet), perhaps? 

Another thing which is more of a question. I assume that she can only breath underwater while in her Mermaid Shift?

As long as you're okay with the harpy and gryphon phases working together. I thought it was a different approach, and something I would give a try. Also added in the background info for Liza, which has been adjusted. I need to finish up the powers and abilities, which will need to include an explanation of what IciQuills do.

I'll look at your background and come back to you some time later today.
