I like the colors in the picture, the bits of purple mixed in with the different shades of blue make this piece pop and the perspective is well done. It looks like it's either doing one of two things; either it's getting sucked into a black hole or it's an explosion seen from far away, it really makes you guess that's why this picture is so great.
The shards near the foreground is a nice touch. Each time you look at this picture you notice another small detail you might have missed before. This is really a great collaborative effort, great job
