Is this image alright to print?

[Simons]

Hi,

I am trying to take part of an image and use it for a print, quite a large one thinking of different possibilities either poster or canvas. Approx 1.2 x 1.8m.

Here is the original shot:

Quite Large*

As you can see i have taken the person on the bike and then attempted to cut him out and place him on a single colour background to match the sky. Is he cut out well enough for a print or would it look stupid? What about the colour, would using a single colour background like that look weird as well?

Any suggestions appreciated!

Thanks
Nic
