Created a path for the RHS of the heart (1) followed by (2) Transform > Reflect [ vertical, copy ]. I did 1 and 2 several times until I was happy with the shape. Once I was hapy with the shape I went back to the RHS and and completed the path (3) , then modified the LHS so there was no overlap (4)
Now it just a matter of coloring the heart to match the official logo.
For the backdrop I pressed ⌘ CLICKed on the layer to load the Smart Object as a selection, used the Polygon Lasso tool [ Add to Selection ] to add the insde of the heart. In Paths Palette I clicked Make work path from selection.
Gave it a white fill, and ⌘T to enlarge so that it encompasses the logo
It didn’t come out that great but was important since it wouldn’t be noticeable once I applied a gaussian blur:15.4px
The heart could a little fuller at the bottom, but that’s just knitpicking. Overall Im happy with the result.
