Well that can't be right because the shadow should stretch out of the left side if it starts where it started on the right side. It's not physically correct.
But you can't just say no to a helping tip. The fact that the shadow is irregular and is physically not possible to do, makes it look like poor work and feels like you just can't be bothered changing it. That's my logic.
I might most likely make a whole clan picture with vectors, but that will takes ages. I already have 2 videos in the making, a competition and another one underway. Plus the whole render thing.
