ah ok! lemme type,,,

OK!! so first things first please know these are ALL my personal taste so most of this stuff you don't have to do!! this is just what I would do!! first of all I LOVE his concept!! very epic and sexy !!! the first thing I would tweak is his color contrast it all kinda blends together and looks very muddy?!? ldk thought that might be what you are aiming for tho I dunno. uhh here is something! https://i.pinimg.com/originals/2a/fa/92/2afa921dcfd1ed15f0b6e0e0fbc5e938.jpg he looks like a warrior beast!! I would give him some cool horns (front-facing imo) and make the blood a little brighter redder give him some bone patterns with the white-grey, big paws with claws so he could bludgeon his enemies also, this is just my preference so please don't do this if it doesn't feel right!! but I would get rid of the circles they look out of place and would look better on a bubbly friendly character imo!! or replace them with more hard shapes like hexagons or diamonds and full them in with white-

the tail also looks a bit dainty so I would do something like uhm a dragon tail with a sharp edge?? idk also I would add a highlight color like blue, red, green or, yellow highlights once again this is an awesome guy and just do what you like and enjoy :)
