My first attempt at foundation double crochet! Do you have tips and tricks?

Hey y’all! I attempted a foundation double crochet! It’s a mediocre attempt, but it’s still an attempt! I followed this YouTube tutorial: https://youtu.be/PCNcKEBr790?si=MzayD03VMlt0gSma

Now I will admit, I felt bold and stopped watching after the first completed chain (only rewatching that bit till I felt comfortable) and thought I could do it.

I don’t think I did great, but I’m still proud of my attempt. Do y’all have any tips or advice? It looks /almost/ normal, but I’m pretty sure I missed a chain or didn’t double crochet properly at some point.
