Okay let me start with first impressions...
When I first look at this image the first thing I see is the lighting or the lack of lighting I should say.
Not sure what you used for lighting but it's just not enough light.
After reading all your comments I see that everyone said the same thing. What you might want to try is using some sunlight in the morning or later in the evening to allow a soft glow of light. If you used the light in the middle of the day it would give you a very hard harsh light creating shadows that make some really weird objects sometimes. For a long time I shot outside until I got some lighting and used towels and sheets for backdrops.
Over all the idea is good and the expression is wonderful. You really do look confused. Keep those great ideas coming.
Q: whats the difference between a conundrum and an elephant sitting on a bun?
A:A conundrum is a puzzle, the other has a bunundrum!
Good take on challenge, might have been better with a better lighting set up not one on camera flash
