Howdy Wrose,
Nice map - I look forward to seeing what the "finished" product looks like. I'd also love to know the scale of the map - are these ruins tens, hundreds, or thousands of miles apart? The use of pieces from an actual map is interesting, but hard to pull off - I tried the same a few years ago and just wasn't happy with it. However, it looks like your attempt came out much better than mine! =)
BTW, I was browsing through your setting and noticed that you were interested in receiving help on it. If you'd like to make life a little easier on yourself, check out Eruvian.com. It's a collaborative world-building website that allows visitors to use simple, web-based forms to publish their homebrewed content in a standard, searchable online format. You can publish a single component - say, a deity, a race, or a spell - or an entire setting.
It also has tons of features to encourage collaborative world building such as a hierarchical ownership structure, setting-specific forums, a community rating and review system, a content request system (a formalized system to ask for help and track tasks amongst collaborators), player and GM-only views of content, player and GM-only forum threads, etc...
Everything's free and it has an active and growing community supporting each other's efforts. The site launched in beta some three-and-a-half weeks ago and currently has over 100 registered users and 800 pieces of published content. Yesterday it announced its first agreement with an established publisher, Blue Devil Games, to become the official collaborative world-building site for fans of Dawning Star, their ENnie-nominated sci-fi campaign setting. And a little birdie told me there's more where that came from. =)
At some point, if the community wants it, Eruvian will print publish the best of the best content, most likely as compendiums (e.g. 101 Best of the Best Monsters/Races/Spells/Vehicles/etc.), crediting the contributors as co-authors and allowing them to be "published".
Hope you drop by and share Tel'Lagaia with the community there....
