I don't have all the most recent models but I've found image generation to be terribly disappointing in most that I've tried in that it doesn't seem capable of understanding directions or fixing mistakes.
"Create a drawing of a cliff in the desert."
Get something passing.
"Add a waterfall."
Get a waterfall that has no connection or outlet.
"Make the waterfall connect to a creek that runs off to the left."
Get a waterway that goes by the waterfall without connecting and goes straight through the center of the image.
Give up on that and notice that the shadows go to the left but the sun is straight behind.
"Move the sun to the right so that it matches the shadows more accurately."
Sun stays in the same spot, but grows while exaggerated and inaccurate shadows show up that seem to imply the backside of the cliff doesn't block light.
