First of all, I would just like to say.... BRAVO SommU
This, is an extremely hot piece of work!!!
My only observation is, would it be better to have the star shooting "upward" rather than downward, as some may make cracks about "Granular going down in flames" (just an idea)
Now, onto some text.....
Maybe somewhere along the lines of something relating to a "shooting star", or maybe adding something to resemble an atmosphere on the idea of "Granular knows no barriers"? or something pertaining to a comet??
I can offer to continue working on these thoughts with you, if they seem interesting. It just takes time to think about such things and then one day... it just hits you.
Sometimes, the simplest way for this, is to jot down a few words which come to mind when looking at the picture and work with them, exhaust every combination of each word. Write down the catchiest slogan you come up with for each word and then work from that list, and so on...
But I definitely think it should not be rushed, as such a brilliant piece definitely deserves a complimentary slogan
PS, don't give away too much
This is more than enough to get everyone drooling
