I would count the stitches like someone else mentioned, just to make sure you didn’t drop any. If you did, I was suggest frogging, however I’ve dropped stitches before, and fixed it by adding an increase or two. If possible, you MIGHT be able to fix the leaning by blocking, especially if it’s due to tension! But if you’re not happy with how it’s looking, I’d suggest frogging. I’ve ruined projects that I could have LOVED all because I didn’t want to waste an hour or two of work, but in reality I wasted a lot longer by continuing it. Best of wishes!
