I don’t think yours is significantly different than mine…

Since this was recorded I believe Blender’s color space stuff has been updated so exact color matching these tutorials will be a bit different. Also Blender has “filmic” color transform enabled by default which looks quite different from older Blender defaults.
If you’re trying to match exactly I’d suggest moving the main bell color a hair toward orange/yellow and away from red. Also get a little more yellow in the inner bell. But again I think you’re closer than you think.
