It's good to see members still inspired to do work with Amnesia. A quick glance at your previous work looks to be a very good project for being your first Amnesia CS.
About your plans here though. How do you plan to acquire the things you've listed?
- How will you get the custom monster? Do you do 3D sculpting or know someone who do?
- Are you a music composer, or are you able to find royalty free music online?
- If you are to include NPCs, how will you do that? Same thing with the 3D sculpting may apply to this question.
- You had voice acting in your other work, so perhaps it won't be an issue to get for this one. But do you have it settled?
Are these questions what you know it will feature or what your
goals are that it will feature? Sounds more like the latter. It's nothing wrong with being ambitious, but be careful about chewing more than you can eat. Make your mod manageable. That's a mistake many make, where they start a project that is too big for them to finish, and then it ends up only partially finished. I'm guilty of that myself.
Just some words.
If you've got it all planned, I wish you luck with your project!
PS: If you're recruiting people, it might be a good idea to have some work to show off. You're showing your previous work, which is good, but for this project, you'll drive a lot more engagement if you have some content to display so that people can judge if this is something they want to join in on.
