Fanciful
I really like your designs for those spirits here as well the ideas behind them, it's pretty creative.
You managed to make them look distinguishable while still looking like related or "similar" beings somehow.
Your color choices are really great. They fit the characteristics you gave each of them well.
It strikes me that the Samhach seems to be the only one without a "three-dimensional" shading. I know that spirits can be flat though, so you could have done it on purpose, but I just thought I should mention it anyway.
As for the writing, I noticed that most paragraphs start with the spirits' names which is absolutely fine, it's just that I feel like Lindach's description should start with its name too, instead of "they". I know it's such a minor issue but I think it would help the reading flow.
"Hospital" is written twice in the habitat section of the Shilach.
The adult and child silhouette to compare sizes is a nice addition generally, but I feel like it's out of place where it is now. It should either have its own little box or the comparison of each spirit with those two silhouettes should each be in the respective panels.
Overall it's an enchanting piece of art that is very well executed.
I hope you don't mind that most of my "critique" is basically just some kind of nitpicking. But there isn't really much to critique apart from that.
Great job!
