Nice stuff! As some who has needed to put ux mockups into images of phones this is cool. A few thoughts.
-On the home be numb-down clear: turn this(pictur of image) into this(pic of image on devices)
-the 3d is cool, but I can also see a lot of benefit to having just real photos that I can put my image in.. i’ve Plopped many designs into stock photos ..this takes an hour or so
- to the above point..consider adding a one time cost. I know subscriptions are the rage for us focus on says recurring revenue, but it’s frequently not what users want.
Good luck!
