Good start. Keep trying.

I think you are trying to focus on the subject and topic of kiss more the image you are working on.

I noticed you honed in the eyes and they are the darkest lines I can see in the whole drawing.

The neck and jaw along with the eyes and ears.

If you can track the placement of the ears you can line up the rest of the anatomy.

Ear lobes to eyes ,eyes to nose and nose to mount, jaw, lips and so on.

My advice? Anatomy study and posing mannequins or draw from example.
