Keldan has a point, spell jars are kind of complicated. I can already tell that for the purposes you’re going for, there are a few things in that jar I wouldn’t have used. But I like the effort and the creative thinking!
As a beginner you could try making a protection amulet, making a protection rune, making stone warding around your space and if you’re feeling like a true wizard, even practice shielding (which can be done for both).
Love seeing your practice! 
Cheers.
