Since the Potara fusion uses the dominant personality of the two fusees, I thought that Luna was dominant enough for her form to be used as the end result.
I had a bit of trouble getting the translucent parts of her mane and tail to look right, but other than that, Lunestia was rather fun. I used an online color blender to combine Celestia and Luna’s coat and eye colors, and I think the resultant colors are rather lovely myself.
Shout outs to and for the inspiration and the Luna vector, respectfully. You’re both awesome!
