Using the paint brush tool
First of all, I chose this image and I selected the paint brush tool and set the size to 117, and then drew over it. At the bottom I then selected new gradient hue layer which makes this image seem like a graffiti artwork, this was pretty easy to achieve because it only required you to change the gradient to get this graffiti look.
For this, I set the brush size very high and changed the color to an illuminous white and pressed twice on the tunnel hole to get this sort of enchanted look and how light is coming out the tunnel.
