Could you throw a little bit of a bright green into #21, this is the favourite so far. It's just missing something. Or, a bit of red into #20? The oval around #19... not sure... I like having something in the background, but maybe something more subtle. it seems to have too much blue/purple and the images don't draw your eye in anymore. #18 didn't seem as colourful so we moved that logo out so we could focus on the others better. We also moved #3 out because of the brighter colours in #21 & #20. Thanks!
