Hi everyone,
I recently wrote a post on my blog covering my workflow regarding the steps I follow when I'm editing a portrait. I also made available a PDF file with the same checklist I use so you can download it.
The post is available both is Portuguese and English.

There are also other articles talking about Affinity and other free resources.
Let me know if it was useful.
Cheers
