Howdie,
First off, nice site you got here. Glad I found it before I got too far into my new hobby/obsession... Building Arcade Cabinets.

I was toying with the idea of building a Street Fighter II themed cab, but didn't want to just re-use the original art.
So I've been working on a couple different ideas over the last couple days here, bored at work, & came up with something that people around me seem to like & I was pretty surprised at how well it turned out too.
I started off with the Ryu Cover art from Street Fighter II Ultimate Edition, then added a random blue Fireball graphic I found in google search, then overlaid the SFII logo. Voila, custom Side-Art.
But when I tested it on a cabinet mockup, it didn't quite look right with the fireball shooting sideways, so I flipped it upwards & the rest is history. LoL
Now I'm working on a High Rez version so I can print it out at about 2 1/2 ft. wide by 3 1/2 ft. tall.
Also, I was thinking of using the other Ryu SFII Ultimate Edition art that shows him from the back for the other side art.
Thoughts & opinions appreciated.
Thanks,
