Tileset, by 
“Moondance” by Gus is a simple and short tileset on 209 tiles, the set is considered of about one generated texture used all over with only shading as varity as well as a few other effects such as the same texture ‘bubbled’ and pasted unto already exsisting tiles. There is also a sprite drawn green alien that can be animated for a dance though his facing angle and even his face remains in the same lifeless expression.
Try using more than just plain textures and draw more objects for the player to place. Up the quality of the texture by using better colors and create them with varying texturial effects using programs like Adobe Photoshop and Paint Shop Pro rather than just a texture. Also try to take layers into consideration: One would want something to put on more than just layer 4 and 8. Creating transparency around the stars and moon would for example let the editor use both layer 7 and 6 in addition to 8.
