Strategy for the concealing and the revealing of your letter / number combination

For my letter and number, I have chosen 10 as my last student number is '0', and 'N' for last letter for my last name. On my island, I'm trying to put these features in 5 different way. Firstly, I have put 10 birds flying around the terrain. Secondly, I have created a road which is shaped in letter 'N'. Thirdly, I have placed a trees in order of 'N' shape in 10 different places. Fourthly, I have put '10' clouds up in the sky where raining feature is placed on terrain. Lastly, I have created a terrain that is shaped in '10' in my island.
