Busstop - Promo board

I'm currently working on developing my own OpenGl (GLSL) shader, It's only been one week since I started the project however I've made good progress and am now beginning to model the main asset that I want to show off inside this OpenGL renderer.
Below are renders from Vray showing off the lowpoly mesh.

Software used - 3Ds Max, Vray, Photoshop.
