I'm not great at photoshop but I just wanted to give it a try. My intention was not to make it much different, I just think some additions such as agent class types might be helpful! Hope you guys like it, feel free to share your opinion.

By using the scroll wheel, you can switch from one agent class to another. The animation and the background look pretty crispy, I just included them to have a concept. Hovering over the agents (on the left) and their abilities (on the bottom right) makes them highlighted so it's easier to see. More detailed explanations of the abilities would be super helpful too, I just included the DPS, etc.
