I like that version of Sypha. It's much better than the Judgment redesign and, I daresay it, the original design : p
There's really nothing particularly exciting about a figure in a plain blue robe, though I don't have a problem with the original look.
This design retains enough of the character's original look while updating it and making it much more visually stimulating. We must also remember that Castlevania is a Japanese fantasy series. You take what comes along with that. And even considering that point, this design is not overly ridiculous like many of the Judgment designs.
