Thanks @str11 !
I usually go with mostly polygonal modeling with a symmetry (mirror) modifier for a project such as this, and then I use proportional editing (with various sizes/strengths) more than sculpting, and then many loop-cuts, extrusions, and some instances of remodeling as the mesh builds in size and complexity.
I first approached this (like many of my WC entries) as primarily a speed modeling challenge, but then, as usual, I wanted to refine it and take it further, as much as I could given my present personal time constraints.
I’m glad to have remembered to fix the head antenna Lots left I would have loved to push further, but I’m grateful to have gotten this far.
Have a good week!
