Playing with Rectangles

I need your help! I spent all day yesterday cutting out sweet little rectangles of coloured glass. I then had a play around with the layout and colours and came up with something I thought I was happy with. This is the layout, you'll have to imagine it with the lead between each of the pieces.

 

Anyway, I went to bed last night and couldn't stop thinking about my design (the things we lose sleep over!). Was my design really what I wanted? I then started to wonder whether I should change it up a little bit, maybe by subdividing some of the rectangles. I've had a little play with the photo above and added a few additional divisions to the horizontal rectangles (a little roughly!). Below is the new (improved?) design, what do you think? Sorry, I should have added the black lines to the first image too, to make it easier to compare.

 

 

So thats the quandry. Should I leave it well alone or get cutting? I'd love to hear from you, please add your comments below.
