What do you think of this bent design?

Just curious how you all feel about this bent design. My main interest is that of the different heights on the sides. I have never seen a bent built like this. Do you see a problem? The post are 8x8 pine, top grade very tight grain.  Thanks!

JBW,
The whole left side of the roof is doomed to fail, in my opinion. I don't know what your loads are, but you have an 8' cantilever on the left post, probably a 5-6' cantilever on the tie, and a low pitched roof with no ridge support. The outward thrust on that side of the roof is substantial, and nothing to hold it in except a joint on the tie to rafter that no pegs can resist, and the cantilever on the tie and/or the post would fail as well. Please consider consulting with an engineer.

I agree with Will, get a consulting engineer with experience in TF design.  I would add it's not really possible to make a thorough judgment on a single bent elevation, so much is missing, such as, framing plan views for first and second floors, roof plans, joint schedule and connections.  The engineer should spec a foundation and footing plan. 

My gut reactions is to reevaluate the framing plan and get a direct load path from roof to foundation in the building core otherwise you'll have a destructive force generator, especially with high posted weakly tied buildings.  Remember, force amplifies when roof systems subside from deflection.

Get help.
