Never again. Took me 3 days because I became stubborn at a certain point about cleaning everything. In the end I settled by avoiding the hearts for convenience and also because they're cute, also I didn't touch the text that was above x-ray mosaic because redrawing that is a mess, especially in high res.
Support my bounties if you like what you see. Thanks!!
