Amateur bakers, how long would a cake like this realistically take you?

didn't know which flair to add for this.

Im just very curious to know how long a cake like this would take others. It was a 10" and 8", everything made from scratch.

I feel like i am soo terribly slow at the entire process 😭 I only make cakes for family & friends (maybe 1 cake every other month) and i don't think ive gotten any faster since i started.
