Looks good to me. I'm not totally convinced by the printer friendly version though - it looks very overexposed, and the actual edges of the flag stones (along the grid lines) aren't very clear. Otherwise - looks great. I'd definitely be interested in knowing how you created it. Any chance of a miny tute? Repped - and welcome to the guild.

As for the style - it's very nice and would work well for a room. If this was to be used as part of a larger area though I'd have to say that the central glow is going to look a bit odd when you lay a few of these out side by side.
