okay ... this is probably because I don't trust myself around "light and airy" ... but, I think that burgundy background just is wonderful!
There is so much light in your blocks, they need something solid behind them to really make them pop - - but, I may be a bit prejudiced by the bad experiences I have had with light colored things ... you know ? As in if I am wearing white, the manure spreader is going to break! LOL
And, I do tend to enjoy things that are substantive in their presentation, so I just don't know that I am being any help at all.
