My favourite is the second collage, although I like all three.
I'm sorry, but I'm also lousy at naming my works.
I think that sometimes it is better to leave the work without a title, so you don't induce people to have a certain reading of your work.
Glad to see you and thank you for your kind words!
You're probably right about the name, especially for such an uncertain genre :)
I just wanted to hear what associations these light drawings evoke.
