Carpe, Always use the best plants for your own seeds. Your patch looks great.
Your pictures are making me wonder a few things.
How deep are you able to loosen the soil?
How deep is the top soil?
What are your plans for watering?
If you use a well has it ever gone dry?
How much humus is in the soil or is it sandy?
Does the soil clump when you squeeze a handful or does it remain loose?
When you pour water on the ground will it make a puddle or does it sink right in and dissappear?
You don’t need to answer my questions for me, those are just some of the things I would observe if it were my own garden. BTW what kind of machine are you tilling with?
