I'm not sure about the sparkles. On one hand, they're pretty distant from the gradient that's going on but on the other hand I sort of like the look of it. Perhaps unnecessarily festive but who cares.
That's blue-orange and yellow-purple done, leaving basically red-green which I won't go to soon. Perhaps for Christmas, but not yet. Not sure what I'll go for next, for now I quite like the look of these!
