Kerry, I'm not sure if you mean in my art personally or in the thread. My moodier art tends to convey a more melancholy mood but you can depict any mood in the thread... sadness, wistfullness, fear, even extreme joy. When you look at something that moves you to feel what is being depicted, you've nailed it.
For example, a color photo of the famous LOVE sculpture in Philadelphia is not going to be moody. A black and white photo of the famous LOVE sculpture with a couple arguing in front of it yelling at each other gives you mood. And paradox... BONUS! Or a shoulder-up portrait of a teenage girl with pink hair smiling nicely for the camera... not moody. Have her throw back her head laughing so hard her mouth is wide open and with her eyes all squinty and a tear on her cheek from laughing so hard... mood! Watch the thread and I bet you'll get the idea soon enough ;)
