Instagram promotion feed design

Exploratoration design about Promotion design for Instagram feed.
I made it in Photoshop with some elements (chess wood, icons, profile picture, background picture, lines accents pattern) that I downloaded from Unsplash, Freepik, and Flaticon.

I arrange all of the elements in the new design with blue as the main colour to support the energy of professionalism that I combined with digital and young spirit through bright blue colours and some light effect there
