One of the most noticeable things that I've done to this original photo is that I've added the Mr jack skeleton face and the classic leather jacket to the photo, I did this by using images of the skull and jacket then using the lasso tool on Photoshop and added it on top of the image.
Then I also used the auto fill tool to remove the original writing and logo then replaced it with my own and then I adjusted the entire tone of the image changing may elements such as saturation, exposure and contrast to five the old vintage poster look.
Another thing I added was the root beer bottle to image and the reason I did the this was because near releasing it I realised that I had to have the product on the poster to furthermore advertise it.
