Overall, beautiful but for me sadly unusable. Colors are wonderful and I love the painterly style. But the yellow text is just too bright and lacks contrast for me to be able to use this because it hurts my eyes. The text drop shadow does help though (but can't be used in the url bar). Also, the little white "x"s to close the tabs are almost totally invisible (but I don't know if you can modify the color of those).

I like poppies :) It's time that summer is coming
