LISTEN UP! Smudging lesson 101!
when ur smudging, don't just brush a color, and then smudge outwards in random directions. brush whatever color with a soft-edged brush, and then smudge outwards at 100% strength with a hard brush. smudge outwards, then smudge inwards. outwards, inwards, outwards, inwards. you'll be able to get different shades of whatever you brushed, and extravagant shapes.
and colors, don't just throw a color on if you're putting it in the foreground (front). make a light part of that color, the color you began with, and a dark version of it. smudge those and maybe play with the saturation or blending modes of the guano.
you did a good job with the top left red colors, but the background pink stuff on the bottom right bothers me, because the red and white are varying, but there's only one pink part that varies. and it would also look better without the vertical white smudging near the right edge. (or maybe just a bit smaller)
and balance it out with bold black text somewhere on the left
