Reply To: What do you think of the topology of that highlighted mesh?
Yes, that is much better!
Two slight improvements; the line of symmetry has a few Vertices that are a bit off. You can use S, X, 0 like this:
then you can set the Merge Treshold in the Mirror Modifier a bit lower (maybe 0.01 mm), because the default of 1 mm is a bit large for such a small model. Might not be a problem, but it’s better to be on the safe side.
The other thing is the this Edgeloop is a bit wonky (not a huge deal, but it’s an easy fix):
You can select it, then press X > Delete Edge Loops (at the bottom of the dropdown menu). Then add a new one with CTRL+R and slide it into place.
