Excellent.  It's important to stick with it and DO _something_, even if it's not
ideal.  Never let the perfect be the enemy of the good.
I like your results.
Now you know more about how "the devil is in the DETAILS", and it's NEVER _just_
"All you have to do is..."

As a computer graphics trick, why don't you try increasing the size of all those
rocks by 10, and then take the whole thing and scale it by 1/10.
The apparent size of the rocks might stay the same, while the spaces between
them that make them look like they're floating (because they are) might be
reduced by 9/10.

If that works, try doing the same with 100 or 1000 instead of 10.

If it's an engineering class, he might not have one - it might be an open-ended
exercise to see what people come up with.

Indeed, there's always more fun to be had, and so very many things to learn.
