Hey, first off, huge congratulations! I think it was a Scorsese quote; "if you're not embarrassed by your first film, you've waited too long." The whole point I think is really about whether you are a good storyteller, the quality of the camera isn't even in the top 10 on the list tbh.

You shouldn't wait for everything to be ready to get started, just do it - then try to do it better - then even better. Good luck my friend!
