Congratulations on launching. It is always nice to see startups targeting that tiny niche market "the other half of the world."
Friendly advice from your neighborhood SEO: owning two sites in one vertical gives you cross promotion opportunities, particularly if one is more linkable than the other (gallery is more linkable than commercial offering). That said, I would give a lot of thought to consolidating your offerings into one site with two facets if you can do it without confusing customers.
Something I've thought a lot about, and I'm still unsure on what to do. You mean, consolidate WeddingType and WeddingInviteLove together? It might be a good win for SEO, but I worry on two sites, while both focusing on weddings, are targeting two distinctly different groups. That was my reasoning for making WIL it's own domain, rather than putting it under WeddingType.com. Still think that they'd be better consolidated?
