Played around with the perspective a little more, still not spot on but as BF said "if it looks right, it looks right"
Hotted up the background and foreground, sort of reminds me of the place I'll end up in

and i deeply regret any offence caused
but if you believe in such nonsense
then take off your seat belt and drive without brakes
and see how far prayer gets you

stygg your hot stuff image would have worked for me
had it not been for the little squares on the bg image (perspective again)
your cube looks to be floating or tilted on end so the shadow wouldnt/shouldnt be there
it is either an optical illusion or the perspective of the two planes is wrong
the two planes being one the cube two the bg

edit: i firgot to say i very much like the colours, the effect is very hellish

Frank the cube is on end and when you say the shadow should not be there, I presume you mean the shadow beneath the glowy bit as there would be no shadow with such a bright object ?

I believe Frank is saying that the cube looks like it's floating above the landscape, and therefore wouldn't have a shadow, at least in that position. If the cube is on the surface then the perspective is at odds with the background perspective.

i thought id try and draw what i mean
i hope you can see on the attached that the cube has two vanishing points
this creates the first horizon
the little squares on the background are so blurred its not easy to find their vps
but having taken four squares you can see a pattern
their vps give us a horizon that doesnt come close to the cubes
and our eyes therefore tell us that the cube and the background are not on the same plane
you can do this exercise yourself with any composite image
i'm not sure if ive explained myself at all actually

Thanks for your explanation and diagram Frank, I think I've got it, I think

I need a serious tut. or vid. on this perspective subject and from your posts, your just the man to do one

@ Egg - thanks for your explanation too Egg and you also would be a good candidate for a tut. or vid.

I'm pushing my luck here now but thanks once again both of you.

im not really up to doing a tut
hope to be better soon
theres loads of info on the web
google is your friend

Did what you suggested Frank and had a look round the Web for Perspective help. I found this one which is one
point perspective, nothing to difficult but is a place to start, I did the door, rug and window with frame. There's a few more things to draw in it yet, such as sky light, I've also got to add the rest of the orthoganals,
horizontal and vertical lines yet which I will need for ceiling and floor perspective, so I'm pleased with this start on perspective drawing.
