Google image search is my BEST FRIEND. I do a lot of prep work just looking at pictures. I would say a good majority of the projects that I do aren't really my idea at all. I just put my own spin on them. I don't want to take credit for something that is not mine. A lot of times I just save the image from the search on a file on my computer so I can reference it later. However, I will do my best to give credit where credit is due.
