I agree it looks really good, just a couple thoughts.
How did you fasten the roof system down to the beams? That roof is like a large sail and under the right (or better said wrong) wind conditions it will have a lot of up lift due to the surface area versus its self weight.
As an added precaution I would use something like these straps...

...to hold that nice roof in place. Or even clip angles on either side of the truss bolted down to beam and through bolted through the top chord of the truss.
The tee plates look like they should do a fine job holding the beams to the columns, but some cross braces from part way up the column up to the underside of the beam at 45deg would help a lot with lateral stability as well.
The columns should be tied down to the concrete/footing as well.
I would hate to see all your hard work get twisted or wrecked.
Or you could tell me to mind my own business.
