This isn't a bad DLC, but I just can't recommend it to most people.
I thought about getting it once, but the screenshots put me off. The characters looked distorted and anatomically incorrect, with poor perspective outlines. This week it was on sale as part of a bundle, so I decided to get the bundle, assuming that for this DLC maybe the screenshots weren't sized correctly or someone made a mistake somewhere. I was a bit shocked to see that the quality of character faces was actually slightly worse than the screenshots on Steam implied.
The battlers and sprites are pretty good, but the majority of bust/portrait art is (1) honestly just not up to par and needs more work to fix them up (2) doesn't work well with RPG Maker RTP, so if you're using RTP portraits you might want to steer of this DLC.
Some people might like Fantasy Hero Character Pack, but it's not worth the money considering that you need to fix several portraits yourself before they look acceptable. There are a few amateurish mistakes you'll notice if you're an artist yourself (distorted faces, wrong perspectives, facial feature mismatches, etc), and thus I cannot recommend this DLC to anyone unless they REALLY love the screenshots or only need battlers/sprites. (I should note that sprites are extremely easy to make in RPG Maker.)
The artist can do better, I'm sure, although the coloring/shading is decent. I hope they visit this project with revisions in the future.
