You have great talent. Well, that is to say, I don't know art, but I know what I like. What you did - I like!
How about a drawing featuring a beautiful young lady (like the person in this drawing) having her stocking-covered feet tickled with a feather? You wouldn't have to show the person using the feather, just the victim.
I realize that a person with your artistic ability has to go with what you are inspired to do. I just hope you find my idea worthwhile.
Anyway, no matter what your next subject matter is, I'm sure I'll enjoy your work!
