Oven Edited Further

 Wayne suggested the centre dark area be lightened, something I agreed with. This is the result of my edits today seen above, next is the mask used to make the adjustments and note that I changed a lot more than just the centre dark area, and blow that is the image before and finally the adjustment curve that works with the mask to produce the image above. Did I take it too far - only time and repeated viewings of the print will help me decide.
