You can use the sheets however feels best for you, but your current approach might become overwhelming after playing for a bit.
What I’d recommend is using a row for each dice pool (or parts of a pool even, if the pool has a lot of different dice).
So currently you would have one row for your class (Knight, d10) and one for your allies (Mouse, d3). Tomorrow you can roll each and write their results in the “Drops Drawn” column before totalling them and adding that sum to your Blood Drops. Then erasing everything from the “Drops Drawn” column ready for the next day.
This way you’re only adding new rows when you acquire new dice pools, and only changing their details as you upgrade the pools.
