(Same applies for your BlackDragonspawn)
There aren't many mesh changes on the model except for a new head and more spikes, but the rewrap is very nice. There don't seem to be any mistakes with the wrap, or in the geometry or in the model as a whole. I would recommend you to add some team color, change the death sound to something more fitting, remove the swimming nodes(swimming death sound and particles) and remaining animations, do some more changes to the mesh, perhaps add some horns\tusks sticking from his body, and add a proper portrait - perhaps base it on the Red Dragon portrait(but that would require some changes with the animations and will generally be a mess) or the Red Dragon Nest\Roost portrait(but I don't think it has a talk animation).
