Thank you for all the comments given in the WIP thread. As mentoined in the WIP thread this is my first project (I started using blender about 4 months ago and doing some tutorials and a lot of reading) and and it was a huge effort to get things done as I wanted them to be. I learned a lot and after all that was the purpose.
Do you mean the composition of the poster image or the image itself. I am quite limited in changing the perspective for the latter, since I do not want to overly distort the poster image, as this represents the challenge’s topic.
Originally I had a different setup for the final image but it had too much focus on the dummy so I decided to change it to the setup seen above. ( You may have a look at the WIP thread to see what I mean)
