Is the 3rd pic/painting from Egypt? Seems a bit Greek-y/Roman-y to me Though given those two/three civilaztions were, at some point, in heavy contact with each other I wouldn't be surprised if some things crossed over on all sides.
It's an illustration of Alexandria between 3rd and 1st century BC. So yea it's not technically ancient Egypt. It would be interesting if this was set during the Hellenic or Roman time period.
