These are nice.
But, just an observation, while you're working on one theme doesn't seem to make it necessary to display all in the same way (unless that's what's part of the assignment, didn't get that). All buildings (except for the egg) are shot from below and straight (or almost so) on. IMHO choosing different perspectives could have made it possible to show more of it and especially the grandeur. Again, just my humble opinion, knowing very well i couldn't have done it better.
