Hey guys
@mgadiali214 Welcome to the forums! You just need to go to the Worlds 2D category and in the right upper corner you will have "New topic" button. Create you topic (with the name according to the Rules) and post your pictures there! Use the "Reply" button to make new posts in your topic.
That's all there is to it. Your final image should be posted there too.
Be sure to read the Submission Requirements also.
@Bohdan_Lvov Here are the Submission Requirements for the 3D category.
"Everything has to be 100% 3D with only minor post-processing." means try to do as little as possible (some color correction is ok though).
Technical aspects are not important in this contest.
