To replace the background that we’ve just got rid of, create a new layer and call it ‘background’. Move this layer to the bottom of the layer stack. Choose a light purple and a dark purple, and fill the layer with a radial gradient, making sure the lighter shade is in the centre.
Right-click on the layer mask you created in Step 02 and select Apply Layer Mask. Next, cut out her left arm and paste it onto a new layer. The arm doesn’t look right where it is, so we’re going to rotate it towards her body slightly. After you’ve done that, merge the arm and woman layers together. Then select Image > Adjustments > Desaturate.
Grab a piece of paper, and something to draw with – this could be pencil, pen or inks. Sketch out some drips, similar to flowing blood. Be as messy and as rough as you want: the messier, the better. Use the photo of the woman as a reference point so that your drips will work with her body when you scan the drips into Photoshop.
