Thank you, George! I had added the photos to Google Drive because I thought it might be the best way to preserve original quality, but I certainly understand the reasons to prefer embedding them directly, and I appreciate you taking the time to do so. I'll take note going forward.
And thank you both for your feedback so far - it definitely does look o-suriage to me too, especially seeing the hamon extending down to the nakago. I believe the nagasa is around 62cm / 24.5", so quite a petite blade.
