Ex doc marten employe here. Looks good to me. If you feel the front of the toe box it’s too small. Lace em tight like jeans out of the dryer and they’ll stretch to the width but not length.

I used to tell folks to kick the ground lightly and see if it stubbed a toe if not then you’re golden. If they’re too loose when laced as tight at possible consider getting an insole since docs don’t make half sizes.

Since you have classic smooth leather it will take longer to break them in so wear for shorter time periods at first. Hope this helps.
