Adding to @jlampel ‘s answer,
Welcome to CG Cookie, we are super excited your here @gabrieljim , and I would recommend taking up the challenges.
This months Space Station Challenge is based on the Low Poly Rocket Course , Its not a competition , its designed as a challenge to help solidify the knowledge gained in the course and to put it into practice with a project.
I’m working on a challenge based on the Fundamentals of Mesh Modelling Course for either August or September, so look out for that.
I would also encourage you to start a progress thread to help you, its great to get feedback on your work, to learn from others, and to keep you motivated.
There is lots to learn and do at CG Cookie, and a great community to help you along the way.
Happy Blending and help yourself to a cookie🍪 , there’s more in the oven.
