LeAndra Dawn has a free Postwork walk through (she uses photoshop) of one of her images. (She is featured in the user stories on Daz's home page)

I put the original post in the Community center https://www.renderosity.com/mod/forumpro/?thread_id=2900436 as I wasn't sure the best place to put this. She also has a patreon with more. So check out the original post The freebie is about 20 mins long, the last one I got from Patreon was 3.5 hours.
