Really lovely work Nina! You are far beyond my skill but I have always wanted to pay you back for all the help you have given me! I don't know if any of this is right, but I did a paint over of the sandwich.
When I looked at this my eye is really drawn to the bottom bun because the values are really high. To me based on the cast shadows it appeared that the light was coming from the top, so I reduced the values on the bottom bun thinking the cheese and meat would likely cast shadow on it, also hopefully drawing away some of the attention.
I added some extra AO and bounce light, but honestly im pretty new at all of that so I just did what I thought may look good. I reduced the values on the eggs just a little bit because to me they were drawing a lot of attention. My version may not be as vibrant and its probably not right but maybe it gives you some ideas and was fun for me to think about! Really lovely work as always Nina!
