I have been asked about how I did the picture of the girl, and how i made the bag fit, here are some pics of how i made it. I work with Photoshop, but you can use any other software that lets you edit pics.
1st i open an image of a silhouette that you like, erase the background.
2nd i selected the silhouette and filled it with color desired.
3- make an outline to the silhouette, and here is the first part done.
4.- in order for the arm to appear on top, I copied the original image and erase everything but the arm.
5.- and apply the same steps before, select and fill.
6.- import the image of the bag, resize it an place it in front of the silhouette, you can do a) erased the bag just down the arm, b) or is easy to just put the arm fille before in fron of the bag, to make it look real. ( I don’t know why i did the other way )
here is an example of how i erased the arm over the bag, to place it in front.
7.-finally, just add some background color, and done.
I hope is not so hard to understand..
