You surely have good skills using design programs, but you need to take a look to the trends in design to improve what you want to offer. For example, gradients, use of many typography at the same design with different colors and non regular reading order makes the designs look a bit old or weird to the viewers. My recommendation for you is to take a look in some actual styles and then you will find a lot easier to create more pleasing works by yourself
