How’s this for the start of a good margarita?

I’ve never made one, but I’m hoping for a 5 star review from the wife this weekend. I’ve already juiced my limes and lemons. I also dumped about 3oz’s of both lime and lemon zest shavings into the lemon lime juice. 2/3oz lime and 1/3 lemon juice.

My plan is to do the 2-1-1 ratio. Also, 3/4oz of agave syrup. Going to shake it all together with ice and strain. Any suggestions/recommendations are appreciated!
