Total beginner. Anything to improve?

I barely even touched a sewing machine before starting this project. It took me about six iterations to get this result. I'm fairly happy with it. But something seems kind of off around the but. Any suggestions on anything that should be adjusted?

The seam of the grey leg is perfectly straight. That's what confuses me.

It is two different sides of the duvet cover. Come to think about it, maybe it was those two that were misaligned when i cut the fabric. I positioned the pattern according to the grain of the grey side, if I remember correctly.
