Please be as detailed and specific as possible.
You can take into consideration any step involved in your workflow (inspiration, research, concept, 2D/3D development, presentation, prototyping, etc.) and/or other related aspects (creative mindset, portfolio design and visibility, time management etc.)
Please don't hesitate to go into detail about any challenge that is related to your workflow and don't be afraid of writing too much.
We'll take the time to read all the answers, and the more in depth you explain, the better we'll be able to understand your needs and provide you with solutions, useful resources and tools.
If you don't know how to begin, you could start with something like "I'm struggling with...", "I find it difficult to..." and just describe what are the daily challenges you are facing.
