That image reminds me of the Monsterous Psychedlic Bubble mix Cd albums, that could be what the FSOL one would like if it was made, nice job Herd!
I guess one thing would be to make the title stand out more, maybe in white or bolded up abit so people can read it. Maybe you can add one of your aliens into the picture as well if you can, they're like your signiture characters!
I have an idea for an artwork, unrelated to Terminal, I'll give you a PM later.
