I don't know what kind of heavenly inspiration hit you when you were making this but it's been on my rotation for months. I don't have the sweetener but I don't really love sweetened vapes. I also added 0,15 FLV oatmeal raisin which is an amazing raisin flavor.

I enjoyed it a lot, but thought it could do with a little more ice cream flavor to be true to your chosen picture.
The rum is very strong in this one, that's for sure. It overpowers the rest just a little bit so I'd bring that down if I'd mix it again. FLV Rum Raisins is strong at 0.5%, 2% is really pushing it to the limit.
I did leave out the vanillin and replaced it with FLV Vanilla Pudding.
