Help/Critique

hello!

i’m new-ish to sourdough baking, this is my second loaf - i made a loaf three years ago but after that kind of stopped. now with all of the quarantine baking going on i’m getting back into it. i just made this loaf but have a couple of questions:

1. The bottom of the loaf didn’t bake flat. It kind of ended up rounded at the bottom edges. It’s a little difficult to tell but it kind of looks more like a slight ufo rather than the bottom being just flat.

2. There are two large air pockets.

hoping you guys can help! thanks in advance!

ps - i didn’t have a lame to score and tried to hack it with a knife. i will be getting a lame soon :)
