Make sure your tossing arm is more vertical before you start your swing; it'll help align the shoulders and help transfer energy better.
Overall, a very good serve, uses the legs nicely.
I'd second what luvforty has already said about the toss, move it up a slight bit but don't toss any more to the right; ideally a slice serve toss should be between your head and right shoulder at contact.
Tactically, a slice serve out side on the deuce side could be a formidable weapon if you work on it!
Thanks for the feedback! I've always had a quick fire motion so i've always found it hard to have a full vertical tossing arm. something to definitley practice though
