What inspired the side profile? I apologise if this seems rude but to me it feels as if you modelled random shapes and called it done (for the sides specifically). It doesn't look reminiscent of anything - it's not a graceful, circular swoop, etc. If there is a design motif, it's unclear what it is. The shapes appear random, which whilst not inherently bad, doesn't look good.
The idea of the bottom piece "hugging" the top is novel at the very least, and I think you might be onto something there.
When you next show this, please consider creating proper renders rather than raw CAD screenshots. They give this IC a feeling of being rushed and perhaps even a little lazy, just put out without the time or effort needed.
