On the other side:
The M2 and slic3r produced this, with the conspicuous vertical bars coming from the 0.10 infill:
From the rear:
A detail of the left hip shows that slic3r distributes the reversal zits, rather than lining them up in neat columns, and the M2 does a much better job of not depositing blobs at reversals:
I picked 1.0 mm retraction at either 100 or 300 mm/s, pretty much out of thin air, but even some fine tuning can’t improve that very much. The zits are recessed, so the retraction may be slightly too enthusiastic.
The slic3r configuration:
