I'm not sure if you are looking for comments / constructive criticism on the 3rd image that you posted, or you want people to suggest new designs, but I'm going to assume it's the former. I have four comments:
1. The photography in the first two images is absolutely beautiful. The lighting, exposure, contrast, color balance, posing, etc. are all exactly what I would expect out of a good wedding photographer and would be nearly impossible to improve upon. However, the photographic part of the 3rd image (ie, your design) is *dreadfully* overexposed. There are large areas that are completely blown, ie, R=G=B=255. This does not look like an intentional creative decision (e.g., a high key look), but an error made by an amateur photographer / graphic designer.
2. I don't know about your culture, but certainly here in the USA, and I suspect in most European countries as well, one would never wish for "conjugal bliss" for the couple on an image that is likely to be seen publicly. That topic would be considered much too private of a matter. In addition, once that subject is mentioned so prominently, the immediate question is, what about the other aspects of married life that one could also wish for, e.g., health, happiness, good luck, money, etc. Here in the USA, if you really feel that it necessary to say something along these lines in text, I would simply say, "Good Luck", and not point out anything more specific. You should carefully consider who the intended audience is for your image. For example, will it be given only to the couple, or will it be given to everyone who attends the wedding or reception?
3. I don't know about the legal system in Nigeria, but here in the USA if someone used one of my photographs without my permission, and especially if they intentionally obscured my copyright or identifying notice (ie, "46ten Photography"), and even worse, essentially made it appear that I took an overexposed image, I would be furious, and if they didn't immediately remove their version from public view, I would get a lawyer to ensure that the did so, and sue for damages to my reputation and use of my copyrighted image. If you haven't already done so, I would make contact with the owner of the copyright (ie, the photographer) and discuss you using his image.
4. Finally, with respect to the graphic elements seen in the third image that you apparently added, IMHO, they are all too large. They cover up too much of the photograph. Other problems are that the final "s" in the text, "Conjugal Bliss" comes much too close to the groom's face, and the ampersand is touching the border of the curvy graphic element. There is plenty of empty space in the photograph to put graphics / text without being so intrusive. With respect to the curved shapes of some of the graphic elements, perhaps they have some meaning or history in your culture, but it is not clear to me why you selected these shapes.
I hope the above comments did not come across as being too harsh, but these are the issues I see in the third image that you posted.
Hope this helps,
