The fire in general does. It looks great, but it’s the one thing that immediately doesn’t look real.
Assuming the non-realism of the fire isn’t a stylistic choice, it’s at least a defect shared with Hollywood VFX.
Regardless, this is fantastic work OP. Thanks for sharing with us!
Rubbery texture sounds like it could be solved by different cooking techniques. Small changes to how eggs are cooked can make a lot of different textures.
