Well, when it comes to making tiles, like buildings, you want to get a reference (search "building" on google images) and look at the picture while creating your tile, it helps a lot.
and to get your game on the MGB's play game list, once you have finished your game, the more plays the game gets, the more likely it will be on the list of games to play. Get the link to your game and post it on the Games Board here on the forum, that will increase it's popularity, and get you more plays.
Hope this helped
