OK, I haven't taken the exam, and I'm no pro at the vignette [so take my comments with a grain of salt] -- but this is what I notice:
1. In general - lateral forces can be neglected. This means you don't have to have your columns lined up vertically in plan [like you do now].
2. Upper roof - the column that you have lined up with the column at the kitchen / seating area can be shifted over. You need to column at the lower roof in the NW corner of Shop 2 anyway, so might as well put the upper roof column in line with the lower column. This will also let you eliminate a column on the lower roof plan.
3. Lower roof - you have columns on the northernmost and southernmost walls at inefficient locations. Shift both to the center of those walls, so that beam lengths can be standardized as much as possible.
Hope that helps.
