Hi! I think you submitted your 250 boxes as a partial submission, so it's less likely to be seen and there's no way to suggest next steps (including giving you a completion badge). I would recommend you submit it as a full homework submission first.
That being said, community critique is not guaranteed, so it's probably best to move on after waiting a bit. I hear there are also critique exchanges on the discord (not sure, never been there myself) if you want more reliable community critique on your submissions.
