She's looking good - but I think the reason she might look as if she's "missing something", is down to the lack of hard, clean lines and edges. Everything looks round and smooth and kinda cuddly - but that could be down to my personal aesthetic. This is just a quick thought, but for the docking pods (I think that's that they are), perhaps you could use the primary hull of the D-7 as inspiration.
