Notice my Fractals are slightly smaller: 1024x771 instead of the original 1600x1204. I'm sacrificing the unnecessary size for a faster, smoother render, which I can now get safely up to 3K density. This one's actually 2K, but the next fractal, Forest of Winter, is 3K and the same dimensions. If you would like them bigger, just let me know in the comments and I'll see what I can do.
