I read the XMen V.S Alien v.s Pedator fanfic and I loved the way you pulled off your pornographic shift in that one.. It seemed the most believable of all of them since you took the role of god, and more or less made it happen to to impress deadpool. That being said it semed like you drug the pornographic bit out a little too long, and the story as a whole kind of looses it's value. I'm not very big on porno in general though so that could be why I lose interest to be honest.
I had to edit to correct the name of one I actually read.. I may need to read through that one again because the last part I remember was the part where storm and rogue were getting dinosaur action. That's why I assumed it was the Jurassic World crossover. Your "double digit number adjectives in one sentence" style helps to create an actual visual scene in my head while I'm reading your writing, but it makes it more challenging to actually remember and critique for sure.
