It's really cute but... The expression is what it makes the drawing totally off.
Though yes, 你 might say that both of them were surprised and such but look at the background for god's sake! It's really romantic since they're cruising on a boat/ship/whatever 你 call it!
And 你 might even say "it was an accident" but I don't see it since the background's perfectly normal.
Here's my suggestion:
The boy should be closing his eyes with his brow furrowed as the girl remains surprised/shocked.
