Pros: Your composition is solid and the eye easily follows to the focal point of them kissing. Your digital inking is strong showing good variation of weight and proper use of it for form. You positive and negative use for inking is working well if a little busy. You attention to detail is also strong creating good textures and shows a lot of dedication to your work.
Cons: The man's face is suffering some construction problems. First his jaw swoops up to sharply which is a feminine trait, males tend to have a jaw line that goes straight back and then turn at a sharper angle. The glasses are not communicating well as glasses and instead are coming off like a malformed eye that is to close to the bridge of his nose.
Other than those points I have made this is a very strong piece.
