Haha, I actually got a lot of inspiration from a Celestia recolor of Lyra, but in this picture it's actually kinda a trace from Raindrops [link] (with a curly Q added in to match Celestia's styleI kinda imagine she really wouldn't care about making herself look really good. She just doesn't care all that much about appearances, since she's not a diarch here and doesn't have a kingdom to represent. So she just leaves her mane to itself, and so it's kinda unkept and messy. But I do imagine it's very smooth and soft, like her personality She's far more interested in being kind and loving to ponies and helping them, than she is in her own appearance.
