My first loaf with my first starter

Hello!

I have made my first loaf of bread with my homemade whole wheat starter. I've been makin the sourdough english muffins here:

for a while, getting practiced up for actual bread, I love the english muffins, have tried them with and without soda, and with 1/2 w.w. & 1/2 white, and all white flour- what fun! all have been pretty successful after figuring out the proper cooking temp.

So here's my bread. any suggestions on how I can do better next time?
