Once A Fool
The giant circle in the center of the page is a waste of space and it's awkward to read your stats at that bizarre angle. It's also unclear whether you write the stat before the word or after the word. Space for ability bonuses is nowhere to be found. Spellbook page is either too spaced out to neatly contain a list of all your spells (so many pages just to hold a level 1 clerics spells, etc) or too small to write down what every spell does in detail (which no one will do).
Mostly just that giant circle. It's visually clever, sure. But when you're playing the game you don't want to be staring at your sheet marveling at how pretty it is. You want to quickly find the number you need. There isn't much to recommend this sheet over a sheet of notebook paper. Sorry.
I'm thinking that this sheet does not lend itself to your playstyle. Nor was it ever intended to. That "waste of space" in the center is prominant because it is what I consider to be the most important part of a character sheet. Sure, you disagree, but this sheet does what it is designed to do.
In your case, however, may I recommend a sheet of notebook paper?
