My god, twelve books? You must be keeping yourself busy. I suppose I might not be of any help (we'll see in a minute), but if I am, should you request advice with anything else, I would be happy to comply. So, don't freak out, everything will be fine. Holly is here now. xD
1. Depending on the audience your stories are aimed at (eg.; romance/drama readers, fantasy readers, etc) and whether or not you plan on including any action or other relevant information in the wedding, I personally think the story would be far more interesting if you were to shorten the wedding to one small scene and continue from there.
2. In regards to the peacock rescuing your protagonist, I doubt that will scare any readers off, especially if they have already been loyally following your stories for ten books; as long as it can be taken seriously, this should interest readers. I would be happy to help further if you would give me more details on the idea.
3. When considering publication, first skim over everything you have written: undoubtedly you will find some details you want to change, or simply improve. The next thing I would suggest is that you share your stories with a family member, friend, or someone that is well versed in English; you are more likely to receive an honest and helpful opinion from someone close to you, so a family member might be best. You must not be discouraged if during your first attempts to publish, your work is rejected. There are millions of writers out there, and even the famous ones had to put in a lot of effort to succeed, including the author of Eragon, whose books were rejected more than once. It is entirely up to you in relation to what to do after publishing (you can write other novels, take a break, or begin working on a completely different subject), but remember, you don't have to rush anything! Writing should be something you do because you find it enjoyable, not a source of stress.
4. Age is irrelevant when it comes to publishing, as long as your work is good. Do you think a company would care if a two-year-old tried to get their writing published? The answer is - yes, if the work was a big squiggly line. But if they thought they would be putting their time into something worthwhile, and enjoyed the writing as much as they would from an adult author - no, they wouldn't care. The only difference is you would probably be especially famous, due to being so young, because that just makes it all the more impressive.
