Firstly you need to go to Layer > New Fill Layer > Solid Color.
You should see a little box appear, when you do change your setting's to match mine.
Now choose a dark purple, I'm using #551a60.
Now go to Layer > New Fill Layer > Gradient.
As you did with step 1 you should see a box appear, when you do change your setting's to match mine.
For the gradient you want a black and white one. Then match your setting's to mine & press OK.
Now go to Layer > New Adjustment Layer > Brightness/Contrast.
Match your setting's to mine when this box appears.
Now match your settings to mine for the Brightness/Contrast.
Your next stage is go to Layer > New Adjustment Layer > Color Balance.
Match your setting's to mine.
Now match your "Midtone" setting's to mine.
Now match your "Shadow" setting's to mine.
Now match your "Highlight" setting's to mine.
Create a new layer above the model image layer.
Now see where the purple square is on the image below? Click on it.
Set the colour code to #d43dfe, then press OK.
Select a hard brush and make sure you change your brush setting's to match mine below.
Cover most of the image in the purple except for a little gap (see image below).
Now go to Filter > Pixelate > Mosaic, then set the cell size to 75 square.
Then change the opacity to 53%.
Click the purple square again (aka the foreground colour).
Select the colour #c97b97 and press OK.
Select a soft round brush using the setting's below.
Click 4-5 times around the image (mine look light already and yours may look dark, your version is normal I print screened this after I changed the setting's - sorry!).
Change the setting's from Normal to Screen.
Click the Rectangular Marquee Tool & match your setting's to mine.
Whilst holding down the shift key click two areas of the picture. I went for the headband & face (your squares must have a gap between them so they don't join together). Once you've done that Duplicate the selection (CTRL+J on a windows, I'm not sure what the code is for MAC though), once duplicated move the layer just underneath the chin of the model and duplicate that layer!
On the duplicated square layer (the very top layer) go to Edit > Transform > Flip Horizontal. Then move this layer opposite the models face.
You should have two layers (as shown below), you need to merge these two layers together (the ones squared in red).
Once done, double click the layer and go to Stroke! Once that's loaded match your setting's to mine using the colour #FFFFFF.
Select the Pattern Stamp Tool, select a soft round brush (as shown below), then look to the right for the pattern box. Click the arrow pointing downwards to show your patterns then scroll down to the bottom of the pattern list and select the pattern I provided you with.
Now check your setting's match these.
Create a new layer above the model layer.
Click about 5-6 times around the image (as shown below).
Now match your setting's to mine. Then right click on one of your layers and press Merge Visible.
Click the foreground colour box...
Set the colour code to #2b2b2b and press OK when you're done.
Create a new layer & now go to your brushes and select the notebook rim brush I provided you with. Apply the brush anywhere on the edit as we'll be moving it around in a second.
Go to Edit > Transform > Flip Horizontal and move the brush to the edge of the right side of the design.
Double click the layer with the notepad rim on it and go to Drop Shadow. Once the screen's loaded match your drop shadow setting's to mine.
Now merge your layers down again then go to Image > Image Rotation > Flip Canvas Horizontal. Then you're done!
This is my result. You should have something similar, I hope this helped and thanks for trying this tutorial!
