I've noticed your work - nice job. You've made lots of small parts of ocean - they won't be visible at the highest zoom level (like the ocean/see a little north of it - the dutch coast line). For that you'll need to create a single bigger landmark instead of those little fragments. Maybe drop a mail to alpha@waze.com to see if they can join them up in a query.

Also, tiles are not generated for those tiles with no roads in them (SUPPORT!!) - you'll need to draw some roads in them, and delete them after the livemap has been regenerated, like here: http://world.waze.com/livemap/?zoom=7&l ... on=5.49155

Keep up the good work!
