Agreed, this is a beautiful ad by Alan Davis, love the little details like Jean reaching out to Scott and Alison hugging Longshot. And of course Ororo laying on top of Colossus because she was a force of nature back then and the last to fall.
And I never noticed before but the pink kid laying on Betsy's leg, who I assume would be Artie, actually reminds me of Beetroot, another pink child Betsy befriended after the Jaspers Warp as shown in Alan Davis' Excalibur.
