I'd add a couple more photos. Also, my opinion is you should have a photo up at the very top of the page before the first text capsule. Do you know how to make the photo smaller by moving it to the right and up beside text? I'd have a full sized photo up top, and then have smaller photos, at least one, to the right at the side of your second text capsule.
I don't normally advocate a full-width photo at the top of a Hub, but in this case I think it's appropriate. The Hub is all about the product and why it's preferable to other alternatives so a "hero shot" makes sense.
Frankly, I would not say this is your daughter's piece. I would simply link to the place where people can buy it as the Source, and say something like "A belly ring made from bioplast".
A few more thoughts - your title is far too long. I found the content very interesting because I have metal allergies, so I'm thinking that a title which attracted people like me could work better, e.g. "Bioplast: Safe Body Piercings for Metal Allergies"?
For your paragraph headings, think of what people would be searching for on Google. Your current headings don't really invite me to read on. I looked at auto-complete on Google and I got "Is Bioplast safe for new piercings?" That should be a heading for one of your paragraphs.
Have you noticed that on the niche sites, HubPages editors are now using a Callout capsule for each heading, instead of using the standard text capsule heading. I suggest you adopt that practice.
If you take a look at some of my Hubs which went through HubPro, you'll see the editor changed all my main headings into Callout capsules (if you select Health and Beauty on my profile then look for the ones that are on Bellatory, those are the ones that were edited).
I found it irritating at first but I guess I've got used to it now. And I figure, if I use them, then it's more likely my Hubs will be picked to move to the niche sites (which is definitely where the money is).
Note that the Callout capsule does have a nice feature in that you can add some additional text, you can use that as a sub-title.
I did find a forum post which gave a list of the sites and what they were each about BUT not by name - and then I found a Hub in the Learning Center which listed the names of all the sites, but no indication what they included (and it's not always easy to tell from those weird names).
I couldn't find a list anywhere which lists all the sites by name and then describes what each one covers.
I'm positive you had another photo (not the blurry tree one) - didn't you say your daughter made them? I do think it needs another photo and it would not be self-promotional to include it, you're misunderstanding that rule. Just state where the item can be purchased from, you don't have to disclose your relationship.
Self-promotional means linking to a site or product that isn't useful to the reader, for the sole purpose of promoting yourself.
So, for instance, I often link to my dance websites from my dance Hubs, because I'll often have an article about the same topic on my website. So I can link to that article, which makes it perfectly acceptable. If I just linked to the front page of the site, they probably wouldn't accept it.
Marisa, I think this is the most difficult hub I've ever done because it's a little known field and there is so little info on it. So can you check it for me now. I'm happier with it now. But I still think it can be tweeked.
Today I received a complimentary email from the administration about an article I wrote which was moved to a niche site about two months ago. This led me to worry about articles that were moved to niche sites many...
I've heard they slow traffic down although I have a few hubs with call outs that are doing well, so I'm not sure what to do. I hear some say they're fine and others that they are traffic killers. Would appreciate some...
I've been submitting hubs on HP to niche sites, and find the turn around time to be longer than a week in some cases. And it's usually a petty thing, not something listed in the rules. I had one hub held up two weeks...
I recently updated an old hub, to get rid of right shifted capsules. I had three, all little "blurbs", additional interesting tidbits of information that the reader might like, and all three were gray in...
