Hi Tail

Tips for improvement:

The explosion should grow MUCH faster at the beginning. use something like
scale pow(clock,1/2) or make the exponent even smaller. This results in a
fast expansion at the beginning and a slower expansion towards the end.
In contrary the debris should be scaled proportional to the clock (linear
movement) but it should expand faster than the explosion itself. I would
suggest something like scale n*clock when using 1/n for the exponent for
the explosion. fiddle around with the values until you're happy with it.

Also could you add more jitter to the debris? imho it's looking too regular.
Assuming your using a sphere with a procedual texture on it i recommend
using several spheres with a less dense texture and scale them with slighly
different factors. when using just a few additional spheres there shouldn't
be too much influence on the rendertime.

Apart from that good start! :-)
