He's a Tressym of about average size (11" tall, 21" long (not counting the tail), with a 3 foot wingspan), with the appearance of a short haired tabby cat with some strange features. First off is his Tressym features starting with ear tuffs more like what you would see on a lynx than a house cat, and then there are the hard to miss wings. His wings are both leathery and feathery in nature, like the segmented  leathery wings of a dragon with long bony fingers holding the leathery membranes apart but with colorfully patterned feathers lining the inside of the wings with the complex pattering and long feathers sticking out at the finger joints like that of a peacock. The extra long feathers sticking out have little purpose than show.

Then there is the oddities about him, first of all he's got polydactyl front paws giving him a some what opposable thumb and much more dexturous toe pads leaving him with a fuax-hand paw of sorts. Stranger is the degree of biolumination he possess that makes him seam almost otherworldly, his fur shimmers in low light, particularly in the lighter stripes, his eyes glow like blazing stars, and his wings light up in dazzling patterns and shed stardust as they move leaving a quickly fading trail of shimmering light behind him when he moves.
