Try looking in the alternate characters of that font, I think Arthur also includes a J that is more traditional.
The panel shape does not suit the lettering.
That letterstyle is from the 40s and your panel is far more traditional/formal.
You don't really need those stripes in the background.
If you are going with the jigsaw idea, try cutting out a big-ass coffee bean as a secondary panel on which to put the Java Jitters part, then layer that onto a background which has a rounded bottom, putting Cafe under that.
Too lazy to sketch something out today.

OK went and shoveled some snow, Maybe try Flash Script.
I really don't like working with red and black.
