My space

I wanted my space to allow a variety of social interaction so I designed it to curve up the hill and open out to two different areas.  I don't particularly like the shape as I feel like it resonates a little of some kind of fossil...

In retrospect I would like to make the exterior shape flow with the exterior to create more cohesion and better form.
