Great work on the images. At first glance I really assumed that a lot of the CG elements were actually photographic pieces that you'd composed together with a CG building.
The first image in particular has a very impressive look to it overall.
I think it's an interesting idea as a structure, the focus of it, like an ear. However, to be honest I find the concept of the building slightly at odds with itself. I would think of meditative practice as being typically gentle, accepting and socially generous (this is maybe just cliché and where this argument loses any traction) but this building seems selfish in terms of it's impact. That's only being reinforced by the decent car parked there in the image - I'm left with the impression of a wealthy person driving over the wildlife to get up there on the weekends just so they can sit in their 50 cubic metres of concrete while the neighbours can't see down to the lake anymore!
