This work started at April 5 one month passed.. it was first time to drawing background without outlines. so hard to me....Changing tone, Erasing and drawing again.. I almost gave up completing this thing and forgot.. during one month. But I just found it today, looking around the folder which i saved my pictures. And retouched it a little.
Theme was "Sonic Rainboom." But now, it is just RD with landscape that is not even similar to Cloudsdale.
