And here's Hydros ref sheet.

Virtually the same style as Julia's, but that makes it a little easier I think.
Now, before I get asked about his name (again), I'll answer it here; Hydro and Julia were originally the dragons of Water and Fire in the very first plot notes I wrote down about Dragon's Tale about almost four years ago now. Being that Hydro means Aquatic, the name fit at the time. But as the years went by, I got older (and perchance a bit smarter?) and really developed the story into something intense and exciting. As it happened, many characters got reworked, most of all Hydro. But I've always liked the first name I gave him, and nothing else seemed to fit. And that's how he's gotten his name.
