My PHP script improvements (need advices)

I have published my new script Creatta and I was very ambitious about it, but in the first 11 days I had only 1 sale. I am already working and improving my script with many new features, but I would like to read some hints and advices from Envato comunity how to improve it.

Regards,

Branko

Do you want to link to the item?

Also, have you considered doing a bit of marketing work for your product?
