a) I was trying to show that I am prepared and ready for the future. I consider whats to come.
b) I used a motion blur which was done to the whole picture. Also, a solarize filter was done just to the head. Lastly I used another motion blur to blur the orangish leave like pictures near the rear wheel of the car.
c) I used a overlay layer blend on the whole picture. A colour burn was done to make parts of the car gold (it was originaly blue). A linear light layer was used to create the pathway of light from the inside of the car to the left of the picture.
d) I used the special brush that creates leaves at the rear wheel of the car.
