Looks nice - that image creates good depth 
Would like to see it in the apron.
Was that one image you found OR did you copy sections and repeat it in layers etc towards the right of the card??
You going to flip it for the right side card so they mirror each other/ facing inwards towards each other?
My only concern would be laying the instructional text over that 'busy' image might make the text a bit hard to read?
Pick a nice bright font colour and stroke the outside of it so it stands out.

Found the image on the net. I'm not that talented lol to create a layered image, not that would look any good though. You are right, instruction cards are harder because of the amount of text that needs to be readable.
Here is a quick play with the blending options. Added some inner glow, drop shadow and a pattern overlay to give it a bit of solidness rather than text floating on the image.
