I really like your cartoon-style.
However, the cheesy snack and dice aren't working for me, for some reason. I guess it is too "realistic" compared to your drawing. I like what they portray and their meaning, but just not the realistic style.
The font for "Totally a novel by Micah Kolding" looks a bit bland compared to your other fonts. Also, do you need "Totally"? Yes, it adds a "vibe" to your cover but it seems to diminish your creditably since it is near your name.
This current cover gives the impression that it is about a person getting stuck in a fantasy world(perhaps one based off a dice-rolling game?)
Anyways, take all of this with a grain of salt. I am no artist.
