I like what I saw too, but I hope there's a bit more than just hand waving/swaying. Though I guess it's more difficult to create a dance for a slower song?
Chisa's voice is really powerful, but she sometimes can't control it (she sometimes seem to scream when she's supposed to be soft), but I find it for myself very pleasant <3
And she had it since forever! I found out recently a clip of her singing Romamtic Ukare Mode when she firstly joined C-ute and she was awesome
