Agree with Fork on everything.
My suggestion to bring back the focal would be take out the effects for Right side. Those are the brightest and most detracting in the piece at the moment.
I kinda like the text but I really don't like it there. I'd probably shift it to the left a good inch and off set the top from bottom a little.
An easy way to bring one colour back is to create a new layer and brush, for instance the purple/pink, colour onto the layer in the place required and just set it to overlay and lower opacity as u feel fit. Sounds obvious but 9/10 times it works just as well if not a bit better than hue/saturation filters.
What i'd do next is bring back some of the lightings power either by burning the bottom right or by using Filters>Renders>Lighting Effects to really make the focal pop a bit more.
