I wasn't happy with how plain the deer looked in the end, and so I decided to add light bulbs to the end his antlers, and to illuminate them I am going to use a brush.

.

This is the original light buld that I used in my image. I then chose a brush that would be suitable to light it.

This is where I got my brush from. You then dowload the file, unzip it, drag and drop into the photoshop brush section. After experimenting with the brush I created the lit light bulb.

I then copied this image several timesand put them into individual layers onto my deer image.

This is what the image looked like after I had put a few light bulbs in place. However I didn't like the look of them in the end, they were too mechanical for the organic nature of my image so I deleted them and left the Deer and Body how it was. So my final image looks like this...

After doing the experimentation with brushes I definitely prefer the uncluttered version of this iamge. The only thing I may change if I could do it again would be getting the model to pose in a better position so the heasd sits better on the neck.
