Managed to make a reference sheet for this technobutt with just a few changes.
His markings.. are hell to draw, those fast forward buttos fff.
But I managed! And I love this little guy. Even added some information of him.
And yeah, I haven't really put on his "wings" in the full body pictures, but that's because it's to show off the markings without them getting in the way x)
But here is Sound in all his glory :3
