I like the shot and can understand how hard it is to pan in a crowd, but I think the ps work has spoilt it. If it was my picture I think I may down a more dramatic blur, a zoom blur or even graduated the blur to the rear but make the rear very blurry.

It looks sharp enough to me, and with the shutter speed used it should be fine,, the reason it may seem soft is to do the depth of field, at the focal length used and the distance you are form the car with the aperture the depth of field is not going to be more than about 2 feet.
So if we said the white line was you focal point then the car being more than 2 feet away will start to look soft, the avoid this you would need to have shot at about f10 to get the dof.
This is a very simple explanation of dof landscape togs use it all the time for getting front to back sharpness, you may have heard about focus about a 3rd in to the scene this is why.

Hope that helps

to much red, like the concept, I would have the teeth showing as well

I like this but I would attempt to do something with bright perspex,either crop it our or tone it down a bit. the eye is drawn to much to the light and not the wheel chair.

Not to shabby for a 1st attempt, if look you can the rear of car is in focus (non pun intended) but the front isn't, as scot suggest try 1/250and work down. The art to panning is to stand firm and swivel the hips, the taken in mind, pick the car over the left shoulder track it until almost square on to and press the shutter but keep tracking car until over your right shoulder. It sounds simple but the is pratice take loads delete loads.
Hope that was not long and it helps

My sort of shot, just getting to deriliction myself is great.
You have captured the tones and feel very well, I may have been tempted to crop it a little on all sides just to bring in closer.
