EotW Part 1 Creature Sizes

I did make some good progress on finally writing Edge of the World [link] , I think I've mostly written out the first part. Right now I'm waiting on my sister to give me some feedback and help me with the lighter character based stuff in it. While waiting on that I'm wasting time various ways, and this includes some attempt to get a sense of scale for the numbers I've given various creatures.
The guy isn't in the first part, but as a guy who's about 6', 6'1" he's a handy reference point. The gal should be about 5'5" - the first level shows them next to the lower level mutations encountered in part one, there's a soldier termite, a scorpion, and a raven. All big enough to have a part in a monster movie, but far from the real kaiju size.
The next level down is to see how big the somewhat arbitrary number I gave to the dragon's length makes her. She's pretty fricken' huge to the human scale, but the next one down shows that she's kind of slight once you get to the kaiju scale. The mutant bat has about a 300 foot wingspan, which I had somehow imagined being nearly enough to just eat a jet fighter despite knowing how big those things are. It's still a threat, probably bite them in half. Oh yeah, the jets, I just kind of measured how big their length and wingspan are, put them down on the page, and then pasted images from Wikipedia to fit in there because I'm not good with technical drawings. They're included in this because there's a scene where some planes are fighting the bat kaiju, even though it's a long distance from where the characters are, I wanted to get a sense of the sizes involved.
The last creature, largely obscured from view, with the two heads, is the first space monster encountered and fought at the end of part one.
I need to get to work on the following parts and hopefully I'll have some stuff done before too long.
