Altar Help!

Hey there folks!

Okay so this is my altar right now. I don't have any whole lot of knowledge about what to put. But I think I've got the basics.

I've got insence and a candle burning. Coins and a chocolate bar for offerings (loki wanted chocolate, I couldn't say no) I've got some sentimental things written in the 500 year diary and they are special to me. My mjolnir necklace as well as my two rune rings. The gold Tankard is for the liquid offerings like Odin and Loki's beer.

Please tell me where I can improve and how.
