I already reached such a big number - 3000 watchers, yay! =D
Guys, thanks a lot for watching me and for your comments! I appreciate it so much!
In gratitude to you I did this lineart:

The document has different layers: 3 heads and 4 tails (canine and feline). It's better to place your layer with colors under the layer "base". You can also change the lineart slightly.

Feel free to color it and share your results in comments.^^
(If you can't draw and color, you can ask your friend or someone who can do it.)
