Why does your projects get few diamonds? This makes me angry, they are way better than many other crappy projects that get diamonds....Maybe this is the problem:
You should try advertise your projects in the chat,but dont overdo it.
Dont update a project if its not a major update
Maybe put out the download link.
And last but not least, its all in the presentation, make the pictures look clear and beautiful. Not that yours are not, but they loose that final flair.
Other than that you should just let the people make your projects popular and let them build your reputation =)

Very beautiful! I think that a download will help you!
