Actually kind of fun, I personally like the hint of the warm yellow in the lemon. As it is a primary, it sets off the blue and adds more punch to it. You might be able to crop more of the dead space at the top.
The glass itself looks a little dirty, maybe thats just the liquid inside. I like how you added the lemon for a complementary color, but since the photo is so dark it more draws my attention all to it instead of bring out the blue liquid.
