General Recipe Trouble Shooting

Chef Jacob I've been working on developing the perfect Lemon Pound Cake like I used to buy at Starbuck's. I now have my own Esspresso machine to make really good coffee at home but I miss having their excellent cake to go with my coffee. Here's where I'm at on my Lemon Pound Cake now... https://app.box.com/s/16kmrqr9356qfrfnufcyw6k6mpz0sd5j My question for you regarding this recipe is... I'm very happy with the lemony taste but in my humble opinion the cake is SLIGHTLY dense.
