Well... the style file isn't perfect: Some animation of the objects aren't good:
- Start trapdoors aren't animated at all
- Water uses only 2 frames, so the animations are ugly
- Exits too aren't animated at all
- Some exits don't work
- Some graphics elements aren't correct, the black square zone around some of them aren't good
Also, for my opinion, it's better to choose different graphics sets than have a huge one that groups each other. But, I agree that sometimes, it's great too to mix styles together to get more styles.
