Just finished playing this, and have to say its a beautiful game from start to finish. It's one of the very few I've actually finished on the iPad, and I will definitely look for more from this developer in the future. From beginning to end it took about four and a half hours, so definitely on the short side, but I don't regret my purchase in the least, it was worth every penny. I'm not usually one for replaying games, especially as I have so many on iOS, but this is definitely one I'll revisit.
For improvements, or suggestions for the next, I would have liked to see larger areas to explore and a more In-depth skill tree, but this is just personal taste. The story, artwork, animations, everything was very polished, this definitely deserves more attention.
