The misadventures of agent Dee

Thanks, glad you liked it! To understand it, you probably need to read "My name is Dee" in my gallery, but it's an awful pun based on the name "Colon Dee". Colon = two-periods sign (:), Dee sounds like the letter D, so Colon D = :D (a smiling face)
In this case it's inverted so it becomes D: (a shocked face)

Great Drawings....!

Nice-nice
