I find the sub-header pretty difficult to read (I'm referring to "Drag drop anywhere...")
You could a) change the font color to a darker shade of gray b) add a bigger drop shadow, c) up the opacity of its container's black color or d) change the background image.
Also, if you create a public git repository (Github or elsewhere) I would - I'm sure others would too - love to pitch in.
That sub header seems to change a bit for different browsers - should throw a little opacity in the container box. Thanks for feedback
went with shadows under the text
It's much better now but still a little unclear (at least in my eyes).
Perhaps re-adding the container and making its opacity higher will look better.
