Still the 476 map : remade heavily Europe, made Africa and Arabia and copy-pasted Americas from
I think your Ghassanids are a bit too far east. Their capital was at Jābiya in the Golan Heights, and I think your map shows this area as being fully under Roman control at this point. Although, the whole issue of showing Constantinople's Arab clients is quite tricky, given allied Arabs tended to be at least semi-nomadic peoples drifting in and out of "proper" Roman territory in Syria and Palestine.
Also, on the 843 map, Crete should not be Byzantine: it fell in about 825 to the Arabs IIRC.
My final ERE point is that I think the Empire should be shown in standard Roman brown/maroon up until at least 700: Justinian's state had far more in common with that of Augustus than it does with that of Michael VIII Palaiologos' dominion, let alone modern Greece.
