A laudable goal! If you succeed, that will certainly also make you one of the richest photographers ever. I'm afraid however that I'm not very fond of your work here for a couple of reasons.
One is that the 'ring in the flower' idea has been done to death; You need to find your own 'signature' shot. Aside from that, I find the use of the mirror confusing; that is, the mind and eye have to work much harder than they should have to see what is ring and what isn't. I'm not a wedding photographer, so I may be off base here, but none of the flowers you chose seem especially wedding-like to me. When I hear 'wedding flower' I'm thinking roses, lillies, and so on. From a technical standpoint, the images seem over-saturated and and to have too much flower for the amount of ring; in other words: Crop more tightly to the ring. Lastly, your lighting needs work. Esp. #4; you can't shoot this sort of reflective surface, especially on a mirror with a single flash. This is a multi-light diffuser/soft-box setup.
All of that negativity aside, I think you've made a good start, and you've definitely got some good ideas. I would approach this from two different tangents. One is to develop your own shot as I mentioned, something unique, which when viewed in an album will be recognizable as a Royal Photos image, and second is to improve your technical skills. This sort of work is actually quite difficult to get perfect, and the people that shoot jewellery for catalogues and advertising are skilled photographers.
Just my $00.02 worth - your milage may vary.
