Interesting project where I had to vectorize a beautifully detailed watch. Can you tell which one is a bitmap image and which one is a vector file? I doubt it. If I didn’t know, I wouldn’t be able to tell myself. You can find out when you preview a larger image by clicking on this thumbnail. Look between upper red dials for hint.
Would you say that both of these images are based on the same picture? Needless to say, Photoshop is a Very Powerful Tool. Especially when it's paired with a Wacom tablet.
This particular illustration had a specific requirement. The message was supposed to be conveyed through images only. No text allowed. How many images do you think there is? No, it's not three. It's not five. It's eight images combined plus some illustrator and photoshop effects.
