In the recipe you posted directly above this post, it's basically a non-tobacco flavor at that point. That is a pretty extreme amount of EM, and the sweet cream/EM combo should be taking over any tobacco taste.
If you are looking for a smooth tobacco flavor and nothing else, try Hangsen RY1 at 3-5%, Hangsen Tab Blended 3-5%, Inawera S'camel 1-4%, or FA 7 Leaves Ultimate at 0.5-2%. If you're looking for a sweeter tobacco, try TFA RY4 Double at 6-12% or DIYFS Holy Holy Grail at 4-10%.
I'm guessing that since you've added vanilla and cream, you want a sweet and smooth tobacco taste, as opposed to a smooth strictly-tobacco taste. Try this recipe, maybe it's awful to you or maybe it's just what you're looking for. The RY4D is very sweet regarding it's caramel side, while the Tab is sweet, but in a strictly-tobacco kinda way. Marshmallow and bavarian are just there to add a moist sweetness that doesn't exist in either tobaccos. I'd recommend not using any EM or sweetener and letting this recipe sit for 3-10 days.
Hangsen Tab Blended 3%
TFA Ry4 Double 7%
TFA Marshmallow 0.5%
TFA Bavarian Cream 1.5%
