Fill this selection with black (Shift+F5). Then choose Edit-Transform-Flip Vertical and move this shadow under the tree bottom.

Step 54

Lower opacity to 60% then apply Gaussian Blur with 3 px (Filter-Blur-Gaussian Blur):

On Filter layer mask use soft black brush to remove blur effect at the part near the tree bottom to keep the hard look for it:

Step 55

Add layer mask to shadow layer and remove the top of it:

Step 56

I used Curves to brighten the tree:

Step 57

Add a Color Balance layer to give the tree some yellow:

Step 58

To add more light to the tree, I used a new layer and take brush with color #fab3b3, opacity and flow 25-35%. Paint along the tree sides as I did below:

Step 59

Make a new layer with same settings in step 10. Use Dodge and Burn Tool to create more contrast on the tree:

Step 60

It's time for most interesting parts of the tutorial - making a heart from branches. Open branches 3 stock. First use your own method to cut out the branches from background:

Use Lasso Tool to take a part from isolated branches and put it above the tree. I used Warp Tool to bend it:

Step 61

Use different parts from branches stock to put on the tree following a heart shape, use Warp Tool or Puppet Warp Tool if needed . I used layer mask to remove any unwanted parts. You don't need to create exactly like mine but can take it as a reference:

I used 15 layers for this branches heart.

Step 62

Group all heart branches layers and name them (I called them from 1 to 15). I used Dodge Tool with same way in previous steps to brighten some parts that are too dark:

Step 63

Make a new layer on the top of these branches layers (within this group). Use hard black brush, 1 px and color #1a142d to make some branches parts more visible:

Step 64

Add a Curves layer within this group to brighten this heart:

I used brush on Curves layer mask to clear some parts below:

Step 65

Use Color Balance to give some yellow to the branches:

Step 66

Right click branches heart group, choose Duplicate Group. Right click it again, choose Merge Group. Now we have a selection of these branches that will be useful in next steps. Turn off this layer.
