After creating the Power Pose image about a month ago (http://www.furaffinity.net/view/24954038/) I tried rendering it in large scale. I realized that the fur was really bad and the model had lots of other flaws which I hadn't noticed before. Hence, I started fixing all the stuff I found wrong with the model:
Redid all the fur, making it much more dense and soft. Fixed some weigthing issues with the rig. Recreated the body, head and jacket textures from scratch. It took three days of work till I was happy with the jacket. The flowers being the biggest challenge!
Next I need to look into her belt, pants and shoes. As they're not visible in this image, I haven't worked on them yet.
I decided to skip the motion blur since I wasn't really a fan of it.
