How long have you been using Photoshop? Nice job by the way. I've used Photoshop for 12 years and my recommendation is to reduce the opacity on the stars slightly and use a different font. I recommend Novecento.
It is really good - I know nothing about photoshop but if possible I would try to do something to emphasize the girls figure on the ring - At first quick glance the girl and ring blend so I suggest that to make sure that no one misses it - You want to grab peoples' attention to make them look closer. Otherwise content, intent and curiosity arousing all done very well.
