Lines above the lateral eyebrows after Botox can be for two reasons. Sometimes when the glabella (between the eyebrows) is injected and nowhere else, they body compensates and raises the lateral eyebrows, this often looks good,but if its too much it becomes like a "spock" eyebrow. The second reason is because the injector treated the whole forehead but didn't put any Botox above the lateral eyebrow, usually because they are afraid of an eyelid droop. No matter the cause, the solution is the same-more Botox in that area should calm it down, but make sure your injector is very experienced.
Botox works great to improve the crow's feet lines. But with animation, it can be that other muscles that you are using to create the smile are over compensating.
