She's really nice....I have one very, very similar in colour and blushing - also around 2.5 k. I bought her as a normal, but she does, like yours have the Cinnamon look about her colour. I'd also agree, a nice dinker project.
I'm expecting the OP to say "AHA! IT IS A CINNAMON! YOU GUYS SUCK!" :lol:
A lot of Cinnamons have a lack of a black outline to the eye stripes, which are usually a pale creamy colour, and should fade towards the snout. There's also fading, or complete lack, of the vertical stripe below the eye.
If you're still unsure, if you breed her and you get these, you'll know she's a Cinnamon:
Either way, she's a very good looking girl. : victory:
