it's not baaad... but here are a few pointers.
first off, There's too much gold. gold should be used to alure a player into a fairly dangerous place just for the sake of the gold, or to give the player some more time if the level is a fairly complex/long level.

un-used items are gerneraly frowned upon, such as the zap drone underneath your name, and the drone right in the middle.

that's pretty much it though. I haven't taken a very long time to look at your level, but I think I've covered the basics. also, try and make longer levels that use up more of the map. 3/5 for now.
