Art Showcase Poster Advertisement

This is a poster design to advertise the end of year art showcase for my college year.
To contrast to the business card idea, I photo-bashed some images together to create an aesthetic beach scene with a selection of tanks.
The tanks in the image are; RU 251 (front), T95 gun motor carriage (front left), Centurion Action X (front right), 59-16 (far left), Panzer II 'Luchs' (far right), Char B1 (back left), M26 Pershing (back right), and an IS-2 (back).
This was by a long-shot the favourite image of mine from the art showcase (between this, the postcard, and the business card), as chosen by the public.
The background is not my own and rights go to the original owner. The tank images were screenshots, taken in the game 'World of Tanks', using tanks in my own virtual garage. I took the pictures of the tanks, but Credit goes to Wargaming for their game.
