Today's Bake. What's wrong with the crumb? Please analyze.

Toast

The open crumb seems to be toward bottom of loaf, not evenly distributed.  Did I under proof, over proof or did I just man handle/get to rough with my shaping?  

 

 

I see no defect. 

Large holes are generally from incomplete degassing during forming.  Degassing requires firmly patting the dough and flattening it, then forming.
