Do I need to fire my architect? : architecture

I’ve been working with this architect for a few months now. We’ve tried three different renditions of plans with lots of minor feedback and reworking along the way. I’ve shared with him my expectations for design and style: old craftsman. This is a second story addition and I want it to build on the existing charm of the place. We got reasonable floor plans after the last revisions, but I haven’t liked any of his elevations. I want to be able to make it work because of the time invested, but I’m just so taken a back by how consistently “off” the elevations appear.

Do I need to fire my architect? Are these elevations good and I just don’t have a trained eye to see it? Does this look well designed to you all with experience?

EDIT: I wonder, could I bring on a designer or some other professional to help him with the elevations? Would that be cost effective?

Here are the most recent elevations:
