Unfortunately, there is not much we can do when it comes to altering the mockups.
Any alterations of the mockups from our side would infringe the copyrights of the designers, who created the mockups originally.
In addition, any alteration to the mockup would be considered a new job, so if you really feel that you want an altered mockup, we would highly recommend to keep searching for different mockups at our stock or consider requesting a custom job to be made.
