Made a few images to add to the steam library entry if your want to run from steam. I'm leaving out the logo since I just use the logo from the main site header.
On a side-note, most of the actual artwork used was not made by me but I modified/used elements of them and fit them into the steam library standard. If references to official artwork are required I can add them as necessary.
