That pesky tattoo. >.< And that's fine. I have a reference picture now. Reptylienx finished their commission not to long ago^.^ Though there is still a few changes.
That's the black butterflies on the leg. And everything is basically the same except Iluvu and not wolf, not to mention the purple butterfly above his tail before the feather things. And don't do the feather things around the tail. ^.^ Other than that the wings, blue eyes, fur color, tattoo's are the same. ^.^ If you could add purple streaks in his tail since the tail will be more fluffy in Iluvu form. ^.^ The ref. Picture below is how he looks. With the purple butterfly on his rump just below the wings tattoo then the purple highlights in his tail. ^.^
And simplifying the wings is just fine with me. I understand how hard they can be. It is a very complicated design.
