I was going to give a sarcastic reply, but ultimately decided against it. I love the Mane 6, but I also happen to be very fond of Sunset. There'll always be fandom favourites and flavours of the month, (Sunset is hardly even the biggest offender in that regard), but I don't think taking it out on random artists is the way to go about this. Take it easy, it's just one of hundreds of thousands of pony images online. I'm sure you can find some you like to give some positive feedback to.
