'Comic sans' is the name of a font.
It's the font you used for the label of your painting.
It's also closely tied with 'papyrus' for the worst font currently in existence.
Probably a good idea to avoid it.

In terms of the actual painting, it's got a great feeling of color/atmosphere, but the brushwork is a bit muddy and undefined. Try using harder brushes (brushes that aren't so soft at the edges) in your next painting as much as you can, and see if it gives a cleaner, less muddy result.
Hope that helps
