The tag alias #60434 halfbody -> half-length_portrait has been approved.
Reason: Can't imagine what else "halfbody" would refer to, fullbody is already aliased to full-length_portrait.
There's a few things that should be tagged as three-quarter_portrait in the results for this, but I can already see a few of those under the half-length_portrait tag so I don't think it will result in any further increase of mistagging. I'll fix them before the alias goes through either way.
EDIT: The tag alias halfbody -> half-length_portrait (forum #353208) has been approved by @gattonero2001.
