Design Help on a forearm sleeve

So this is the general idea of the tattoo but I know i need to either get rid of the Kanji or the Spider Lilly. My question is what can I do to help eliminate the blank space without over adding? If someone can give ideas that would be much appreciated.

Ps. Not a great artist
