Warning, random observations follow...
One thing that caught my eye: are you sure that door to the inside opens that direction? Maybe it's a regional thing, but most house-to-garage doors out here open into the garage. (Probably doesn't matter in your current layout, but just something to keep in mind.)
Also, is there a door in that opening between the 2-bay and 1-bay sides of the garage? If there isn't, you'll probably want one, especially if you're going to use it as a finishing room.
On a completely separate note: I haven't used any of them, but there are several cheap software packages out there for DIY kitchen design etc, that provide 3D views of the layout from different angles. Might be useful for visualizing relative tool heights and other tricky bits. E.g. is the sander taller than the jointer? Will you need to move the planer to use the jointer? Things like that.
(Reading the previous paragraph and looking at the diagram, you probably want to swap the jointer and planer locations. Since the planer will be mobile anyway, its 'parking place' isn't critical.)
Yoga class makes me feel like a total stud, mostly because I'm about as flexible as a 2x4.
"Design"? Possibly. "Intelligent"? Sure doesn't look like it from this angle.
