Yeah it’s a big mishmash of various vaguely ‘antique’ ideas and aesthetics all piled together with no artistry. There is a pyramid in the background and what looks like some generically helenistic-ish columns in the midground. Both appear ruined which is yeah whatever. The bloke at the front is shirtless with a distinctly modern physique, wearing a helmet that although it probably fits whatever aesthetic we’re going with here doesn’t in fact line up particularly well with anything historical. Aiaiaiaiaiaiaiaiaiaai. I think the sea peoples liked to wear nice little pointy hats of various kinds, and the architecture of the period contemporary with the Bronze Age collapse probably looked quite distinct, and certainly more colourful than I was expecting.
It looks like it's supposed to be more greek, since the romans weren't known for fighting naked, whereas we think 'greek' and we think shirtless. Also romans weren't involved in egypt in any serious way till much later. Whereas the 'sea peoples' seem to come from roughly the sphere of mycenean influence, even if they don't all seem 'greek'.
