Must admit, I'd forgotten about this - I bodged it together in about 5 minutes! I know I could design something a lot nicer and tasteful than this! I've come to the conclusion that once I have graduated I will spend some serious time designing a full piece of sideart for my cab (so watch this space)! Should be able to do a far better job as I am studying Graphic Design! As mentioned in the original post this was just a rough mock up - that certainly wouldn't be the typography I'd go for!
I disagree with those that said it being busy was bad - perhaps this is a little too busy but I feel arcade machine artwork should be bright, brash and colourful - as that is generally what they are in the arcades! They need to be, to get noticed amongst all those rival cabs!
As I mentioned before, I want to do something generic (in the sense it doesn't revolve around one particular game!) as MAME cabs are there to play lots of games and not just one - it wouldn't seem right or authentic to me!
Well, come the summer, I will have something very different and much more exciting than this - thanks for the feedback guys.
