What else have you done to try and build a relationship with her? How long have you been working on this? What do you mean by "winning favor"? Are you interested in building a worshipful relationship or are you just hoping that she'll take a liking to you and bestow all kinds of blessings? I'm going to be honest here, some of what you said seems to be coming across as rather flippant, but that may be due to the shortcomings of communicating by text, and you say that you're new to this so I'm not going to make assumptions.
Building a worshipful relationship. By "winning favor", I mean, not making her angry. I'm not trying to use her, I am trying to worship her, and make her happy the best way I can with whatever means I can use. I ask for blessings when I really do need something or to help worship her better. Sorry if anything came out wrong.

I give what I can to her for sacrifice, like lavendar, olives, barlie, and probably later some of my Thanksgiving Turkey and other food. I would probably be punished severely by my mom for burning offerings. I do my best. When I can, I'll replace the picture with a statue, and the small bowl with a bigger bowl, and put incense holders on my altar.
