Too simple, too repetitive, icons don’t have animations, the phone is 2D… which would be fine if it looked somewhat stylistically sophisticated, but now it comes of as “blah” low effort phone graphic. The whole animation seem too static, transitioning from one slide with animated text and images on screen to another. There’s no cool transitions, or idle animations, or slow camera movements between all the scenes which would make everything look more lively, dynamic and awesome
Look at something like the top results here: https://videohive.net/search/iphone%20app%20promo
Then back at your animation, and reevaluate if you really ever had a chance of getting your project approved, when the competing authors have templates which really well execute all of the things I mentioned above, that your project lacks in and then they maybe even go the extra mile and add some unique really well-done editing to music or bring some other nowel ideas to the mix.
P.s why do you need 4 tutorials for this template? I can’t imagine any customer wanting to watch 4 tutorials just to use one template. Either consolidate everything into one tutorial as to not to scare off customers by the perceived difficulty of use (cmon 4 tutorials!! it must be soo hard to use if I need so much learning to do). That one line of 4 tutorials does more damage to you than good marketing I think
