It looks good, but it would be much better if you used the right font for the text.

Yeh, when I've got the time I'll put a similar font on. It does have the correct font for the wallpapers though

Gill Sans was my guess, but looking at the R, I'm certainly wrong.

Thanks for that, I have a new wallpaper!

I just have a nitpick: I think it should break the two words into different lines, like the original does. I first thought it was because the word I chose was shorter (I used "WAVE ON", as in Hendrix's If 6 was 9), but it happens with "CARRY ON" too.

Yeh. I thought that too, but it needs some more general tinkering anyway. I'll get round to it at somepoint

on my screen the background color of the crown is a different red than the rest of the page

Hmm, I'll look into it

The lettering is what makes the original poster. The original poster was most probably hand lettered by a talented lettering artist. Arial doesn't come remotely close.

Especially the capital "r". Arial's "R" makes me want to turn away. "I'm a capital p, but have a protuberance!" Its leg is about as graceful as a heavy duty shoring rod that has been heaved to, propping up an obese person. "Spare me that next step!".
