Well I did this or tried to do this quickly but it turned out for a long time just due to the fact my cat kept sitting on my tablet, so here it is! People need to design more felines! So go ahead and give it a go. I'd enjoy to see what others create out of this, yea I know its simple, its not even an entire tiger but.. XD OH well maybe next time.
My really own rules.
1: Don't claim as your own.
2: Leave my signature
3: Have fun. =3
If used elsewhere please give credit to my ImmortalZImbalance Deviantart account. Thanks you. =3
Edit:
Thank you for everyone that has colored this in, I didn't even realize it caught the eye of this many people. So in 'celebration' of my first editable having 'as many' I've actually updated some of the lines and it gives you an option to add more whiskers, or keep the original lineart. I also added a layer for the mouth shading. It was originally suppose to be four teeth; but I notice it looks good with only two teeth visible and you can barely notice the other two when its shaded. So there's two more new layers for that. One shaded for four teeth, the other for two. If you have any questions about it just ask. =3 I hope it was a decent upgrade though. O>.>
Tip: Just color in the 'color me layer' and that should do the trick, turn on or off the other options just as extra whiskers, original or new lineart, or shading for the teeth. =3
Edit 2: Just added a color layer. Aye, I know this should have been done ages ago. Added a bit more eye shading. Not really great since I'm not too keen on Oekaki but it is something if you want to mess around with it.
