Hi! I suggest improving the animation of the pop-up photo images. As far as I can see from their behaviour, you use Container layer for photograph inside which there is a close button and a description layer. When "close" button is clicked the layer is tweened to width="0" and during the tweening, "close" button and text "description" are "squeezed" making a confusing narrow stripe. This must be avoided. Do this:

If opened, the layer is tweened to its width and only after that the "close" and "description" layers are tweened to alpha="1"
And alternatively, if closed, the "close" and "description" are tweened to alpha="0" first and only after that the layer starts tweening to "width=0". In this case, visual deformations of these layers shouldn't be seen.
