I've wanted to draw some of the post-Insomniac and reboot dragons as if they were from the original trilogy. In my head Ember and Flame are siblings and belong to the Peace Keepers family, Spyro's an Artisan and Cynder is a Dream Weaver. I tried to keep their colours as original as possible, but I had to fix them a little bit to make them fit properly to their families (spots on Ember and Flame, Cynder's claws and horns are different colour). I also had an idea that if Cynder is a villain and belongs to DW-family she could be giving other dragons nightmares instead of dreams, right?
I took some reference from the first game and wanted to make these four resemble the already seen body types in Spyro the Dragon. Ember's a muscular and buffed, tall dragon like Boris and Ulric. Flame's inspiration came from Titan and Ragnar. Spyro is something like Nestor and Lindar, and Cynder shares similarities with Lateef ad Azizi. I also have a headcanon that instead of having sideburns and beards, female dragons (in every family) have extra horns.
Ember and Spyro are discussing about important leadership stuff hence they have just been promoted as the Leader of Peace Keepers and the Leader of Artisans. Cynder and Flame are arguing about something, perhaps Cynder giving him nightmares.
