Hmm interesting design. I would suggest adding some vertical beams between the rafters in the glass roof section. Just to separate the wall and roof a bit. Also try and find another material for the roof, so that the walls and roof aren't made out of the same material. I like Fitted Abyssal stone for roofs. Kinda looks like real shingles.
Also a bit of work with microblocks always does wonders. It looks like all the materials you used are mostly vanilla, so you should have access to microblocks for most of them. For example you could cut down those oak log end beams sticking out to a slightly smaller diameter.
