There shouldn't be a "sight" in the 3rd panel, it makes no sense =/ Also, Horo should O_O in the last panel. It's like this guy/girl has no idea what expressions are. I mean seriously, a surprised crying shocked blush?!?
... I think the expressions look fine. Shock and tears can go hand in hand, and the blush is just to make her look cute. The problem is her eyes look sort of bored, but it's not too prevalent.
