Ken accurately enumerates the many variables that affect the sound of an instrument, and you have two very different instruments here in terms of size, design, wood, etc. You even tune them to different keys and different modes! In short, they should sound different.
In general, most luthiers have a consistent feel and sound, but within that consistency is room for variation depending on the specific model, the woods chosen, the bracing, etc.
