Just something a little dynamic to test out my handiness with Paint.NET.
Technical stuff: I used a fair amount of motion blur for this image (as you can see), and some Gaussian blur for the sparks. It's not really all that realistic, but I think it's a reasonable first go.
If this were to actually happen in TF2, I'd lose. I have 10 less hitpoints and I'm absolutely rubbish at close combat, let alone combat in general. Plus, Eliza's loadout (as far as I'm aware) is the Blutsauger and Ubersaw, so she's more inclined to combat.
