Their Secret - Month of Love Challenge

I am participating in the challenge called Month of Love, that I discovered thanks to the deviant & Twitch streamer stevie-rae-drawn .
Each week, this challenge has a theme that must be completed.

This first week's theme was "Secrets".

I chose to make 2 girls from the 19th century kissing, being viewed through a keyhole to suggest the secrecy of their love.
I am satisfied with the final artwork, even though I would have liked to make it a little more detailed...
