The character art and various battle effects look fantastic! The combat is very cinematic with all sorts of neat animations and a very active camera! The dynamic interface elements are also suitably matched to the style. If you want to expand the game, increasing the pace could be of benefit in keeping the players actively engaged in things. Wumbreon has done a good job with the music I think the track is very suitable for what's happening and there are proper sound effects for everything you're doing.
Channel-based skills are a really neat idea! Since the channel already add a good degree of chance, you can probably remove some of the other luck-based effects, like stripping hitting at 30%.
It's a very impressive battle system with a lot of care and polish! I am curious if you intend to keep going, I think that even a single update to add a story that spans 3-4 battle scenarios with the same cast of characters and skills would be a great way to showcase the full potential of your work!
