It works ok for an end of post logo,
but it works awful as an avatar.

It is way to busy to be scaled down.
People would only recognize it from it color.

One of 9 is not readable in the logo.
And the "raindrops?" do not apply ... the do not have an continuity so you cannot be sure where from and where to they are going.

To make this into an icon, i would get rid of at least one of the rings.
Then completely clean up the background. (no splatter)
And then work on shading the tree to give you a rendering that gives an appearance of a tree. Its all in the color variation.
