I need some Graphic Design for Mobile game app for all iOS and Android devices.

Game will have a main menu and then endless game play. The menu options and gameplay screens are similar to flappy bird. Need someone to create original graphics for me and formatted so that it fits all iPhone phone sizes, as well as iPd and iPad, and Android as well. Please respond with the number "23" in your first line of your response so i know you read the full description. I will provide small milestone AFTER i see first drafts of your idea and remaining full payment after all work is completed. Please include your best 2 or 3 game graphics that you have designed. Thanks
