The original poster was only being promoted via VK (Russian equivalent of Facebook) and Facebook, so it didn't need to be Instagram aspect ratio. Creating images with 4:5 aspect ratio is a challenge for posters because of all the extra information you need to put on one picture, so I decided from the beginning to have white space around the main figures of the images of about 200-400px.

Another challenge was to make it at least remotely similar to works of Hieronymus Bosch. This wasn't necessary but would greatly benefit the overall integrity of the exhibition.

Bosch is known for a very bizarre and detailed style which would be very hard to recreate, so I offered to use as reference his work Tondal's Vision which is centered on the head and could be a perfect way to attract viewers eyes.

The original layout with desired typography I received from the organization team looked a little... Let's say abstract. I digitalized it to make quick changes on the go.

I didn't like the way these posters turned out mainly because of the typography, so I proceeded to convince the team to try something different. My idea was to leave the key elements but rearrange them and change the typefaces of the text to make it more easily scannable and readable.
The final results pleased everyone in the team and the posters were released to the social media and some of them are planning to be printed soon for the winter season.
