One of the major contributions I made to Syfy Monster Island were the boss intro screens. The boss battles lacked any kind of notification for a while and I suggested a flashy intro to create excitement upon landing on a boss. So I designed a sort of template that had could rotate palette depending on the boss and then have a snippet of animation of the boss before doing that slow motion thing. Here's one with Megacroc (A Drew version of the Syfy creature):
It echos a sort of 60/70s horror film look with kind of rough paint splotches but since it's for a Facebook game, it retained an amount of color and cheeriness. Here's my test image using Pterodactyl:
And speaking of Pterodactyl, I think the animations I did for him are one of my favorites in game.
