lol, this is one of my favorite photos in terms of subject matter! A few things I think would have improved it a little, though: 1. desaturate the red a little 2. try not to blow the highlights (e.g. by using lower ISO, smaller aperture, or using exposure compensation), 3. watch reflections which gave you the weird green thing in the middle of the shot (maybe by using a different angle). maybe a different crop in which taxi plays a more prominent role.
For me, I would like to see this photo rotated counter-clockwise so the taxi was on "even" ground. Also, I find the telephone pole distracting. I do get the irony of the cab company name and a cab with no hood though.
