It's tough to say exactly since your file only has the charts, not the actual transactions. In terms of categories I think you're alright (assuming your rent includes your electric/gas/water bill and the categories are otherwise complete.)
I would look at your biggest expenses and see what can be taken away from those.
Charting out each and every expense is great to get a sense of your finances, but once you've adjusted your behavior to Mustachian-levels just a rough bit of accounting is all that's needed.
