Drinking buddies

This one was tricky. In the original photo you could only see two zebras. Then when the sketch was very advanced I discovered there were to many legs. There was a third zebra behind the two first animals. I could have erased the extra legs but it was a bit late allready. So I added an extra head. I think it doesn't looks right, but I couldn't think of a better solution. J.A. sugested me that a "hint" of the third zebra's head could have been beter. Perhaps. Still, I hope someone likes it.
