50% Whole-wheat sourdough

It’s my first blog post here, I’ve asked a few questions before and lurked a lot but thought I’d post a loaf for the first time! Here’s a simple 50% whole-wheat from the weekend.
The wheat is an organic/biodynamic milling wheat from Four Leaf in South Australia and was milled at home on my Retsel Mil-Rite. The other 50% is an organic bakers flour.
The levain was fed 1:3:3, with a blend of fresh milled rye and organic bakers flour and left to ferment for ~4hours.
