This looks nice! especially the colored version
you could work on the depth a little bit more though
Like the part of c4d in the foreground, you can blur that out way more
and also sharpen your render a bit more, cause right now it seems the background is sharper than the render itself
And the music notes are a nice touch but the ones in front of his guitar and hand,, I'd remove those, they look out of place
Love to see a second improved version, but this looks nice already
