that is the link to a tweet that has a picture of my base what should i upgrade next? or should i upgrade walls?

I would upgrade the xbow. Xbow and inferno towers are the most dangerous.

I would upgrade wiz tower first since your xbows are so low

then you can upgrade your xbows to level 3

Personally, Wizard towers will work better for you, They can one shot a lvl 5 archer and you dont need xbows alot at th9 when farming.

If you can raid more than gets taken from you, you can save up. If not, do walls.
