I hope I didn't mess anything up. ;n;
I perceived this species to be more canine-like than feline-like, so I'm really sorry if it was meant to look closer to a feline. ;n;
Now, about the drawing...
I have all 4 stages on separate layers. I added many types of horns/antlers since I wasn't sure what you wanted those to look like. There is no shading on any of the horns, so if you want me to add that just say so! c: The layer for each horn/antler applies to both the adult lineart and special lineart. The juvenile and baby lineart don't have the full-grown horns.
As for jewelry/earrings, I drew them all at once and thought that maybe if you wanted less on the image you could just erase the extras. :3
If I messed up on anything at all, please tell me! I'd be happy to fix it. ^^
Please don't remove my signature, etc, etc. :b
Enjoy! :'D
