Step 1: With the Procreate app on iPad, I modified the image I found (see photo 1), trimmed it to a square, so we get better details of his face and the clover leaf, and then changed the background glass panel to look like the lights are coming out from his halo (see photo 2)

Step 2: I upload the image to Silhouette Studio to process. 
    First: With the Trace function, I vectorize the raster image (see photos 3 & 4)
    Second: There were some lines were too thin, and some lines were not very smooth, so with the 
            Edit Point function, I was able to modify them. (see photos 5 & 6)
    Third: For the facial feature I want to just engrave it, so I need to separate them from the rest of 
           the image, with Knife Tool, I sliced the facial features away (see photos 7 & 8)
 

I am thinking of making a 5x5" project. so:

First: I create a 5x5" square for the backing

Second: I changed the size of the image I prepared to 4.5x4.5", added a thick border around to 
       make it to 5x5"  (see Photos 1 & 2)

Load the SVG to your machine, I set the red outline for the cut, and the purple outline for the engraving (see photo 1)

First, engrave the facial features, then cut out both pieces (see photo 2)

Used the original photo as a reference and the glass image as the guide, to color all the glass sections with acrylic paint pens onto the baking piece. (see photo 3)

After the paints are dried, glue the image layer onto the backing.

Carefully squeeze the UV resin into all the glass panels, and put it under the UV light to cure (see photo 4)
