hmm...
There are a few difference like the marking used on the tail, the shades of blue, and the back mane but it does look alot like Ramine... I guess it's up to how Ramine feels about it. I mean at least the person isn't named "Ramine" or "Tenda"
Maybe it's Tenda's long lost sibling... (If you were suspicious it probably would be better to pm a mod about this sort of thing to see what they think about it although I'm guessing it's probably not to serious since it's not like a total impersonation with name and all)
