Hello for the proposed challenge whose theme is Inspired by Art History Cosmic Creations. I created this gif which took me two days to design it.
When I read the challenge project the idea came to me right away. I just had to find the images that I was taken for the most part from the same place exactly where 
ArtVee
The Met
National Gallery of Art
Here is some link where I was looking for the images.

I'm not going to show everything because you won't get to the end of my post. To keep it simple I downloaded 13 Images of paintings from various artists.
Plus a photo of an egg on google image.
I generated 5 Images with an AI to find skulls and fridas
Now, so that you can have a precise idea of the work, I reworked 100 images with my little Photofiltre software.
This is why I can't put everything online, it risks being worse than interesting. At first I copied my images so that we could see the work but then I realized that the work was going to be very long. Therefore I only made some copy.
My base photo the background that does not change
The Mona Lisa I don't need to introduce her to you, she is known to everyone
This old poster found on the site that was advised
The peacock which also comes from a three recommended site.
The egg that I found on google
His five images are the basis of my creation sof the egg which is him this moves and disappears
I cut out the Mona Lisa the old fashioned way. Why in the old fashioned way because my software is not equipped with an aid to divert a background.
A bit of black and white
Cutting out the face then I turned this face to give an effect when it falls
Same thing for the mask at the end which is ejected by the blue egg
I was also forced to normalize all my ready-to-use images in the same format to make the font work easier for me.
Cutting the peacock to make it transparent
Same thing to imitate them with their machine gun. I reversed the direction and also changed the shooting angle to aim diagonally.
Decoupage of one of the many faces that contribute to the GIF
All are from real atiste paint. The frida and the skulls are made by an AI that I generated with my computer
Setting up speakers for my animation
If you take the time to look a little more at this image I melted the trunk of the tree where the peacock perches on the mountain I pulled a can of eternal snow at the foot. I wanted to blend the base image with the Peacock.
a photo of the assembly assembly
Some painting images downloaded but not all on which I cut out faces
Thank you for having the courage to follow my project
