First,I saw some of these elements here and there and it is not allowed to use other people’s elements in someone work because it is someone own work and his/her invention.
Second, It is really basic and simple and these days customers demand something new and original with ultra specifications as the world in a state of development my friend.
Keep developing and work
Thanks you for help
You used hand drawn elements from other author. You can´t do that and can get some troubles because of that.
And as @HardEdgeie said, your animations are still too basic as I mentioned too in previous works of yours. And try to change text font because it doesn´t look very nice and is outdated.
