I feel so lucky to have encountered your work. This is such a beautifully intimate moment, and (like so many others) it blew me away when I saw it in context on the page. Thanks for popping it out on its own!
Maybe it's me, but in addition to love I also see a lot of pain in Ally's expression. She carries a lot of pain and guilt inside her and has a hard time expressing herself outside of being a dom. While a dom, she is confident, but as a person she clearly lacks that confidence. She clearly has great fear of rejection and abandonment. In this illustration I feel you can see the love between them, but I also see fear on the part of Ally that she'll mess up again or do something that drives Lisa away. You can sense that for someone who has been as alone as Ally that she would be utterly crushed by losing Lisa and fear of that haunts her like in the moment above.
This is my favorite romance story so far, and I think this panel, when it appeared in the comic, was the most powerful image I'd seen in romance. I've experienced moments of clarity like this where the senses just blaze and try to catch the whole moment of satisfaction and happiness.
