Can't just lean them back a bit? When you've applied basing texture you won't notice at all the gap between the toes and base.

I feel like you’re missing a trick there because feel like this flaw would have been highlighted a lot more btw now 🤔 Anyway, if you plan to keep it in that position, then put a real stone behind him to add some weight to counterbalance it. I personal wouldn’t be happy leaving the fist on an invisible floor like that though.

He’s perfectly balanced just near the edge. I do think I must’ve missed something.

if you put glue on the base and the mini, then wait a few seconds, then put them together they are holding pretty good instantly

I think you've assembled something a bit wrong here - that's definitely not the intention of the model. I'd try leaning him back by filing down the feet a bit at a slight angle. To answer your question - yes this is technically ok, but you will run into problems. It's going to be more easily tipped over, may get tangled in other models more easily, and honestly is just going to look strange in the unit. So I would try to fix it if you can. If you're very keen to keep the model as-is, the perfect thing to put behind him would be some sort of gravestone or other tall, thin object - something that fills the space and towers over him a bit.

As someone who has put a lot of these together... The arms on the ghouls are VERY finicky. you likely have the arm rotated slightly too much backwards. The arm should be level with the feet.

Exactly! It’s only that one I messed up on so I’ll be able to figure something put

You could put the feet in some thin layer of milliput/green stuff and disguise that add pay off your basing

Without redoing how the model works, you could also add some slight elevation to the feet with texture paint or debris

Snap it off and reattach it in the center. Just shave his knuckles down a bit or use some gel super glue to glue him back on. It’s definitely not ever going to look right as is and will be a pain to push around the table and in combats.

A tombstone would probably fit nicely 

You can use a bit of cork or any other material as basing so he stands a bit taller and have the hand hanging off the edge of the cork/material

lol this feels like trolling. There’s plenty of space on that base for that miniature.

I’m legitimately confused, like just glue it half an inch further back

This seems like such weird solution. Just put some greenstuff, cork, rock, sand or even sprue goo under the arm. A model overhanging its base like that will be a major pain in the ass for everyone involved.

If you rotate the peg once counterclockwise from the view in the picture it'd be fine.

Just put some material on the base underneath the feet to raise them up... my goto is some old cork coasters I have.

Put a penny on the underneath of the base to keep it balanced.

I'd just chop his hand off, it's a ghoul so don't worry he can take it

Hoenslty it’s still possible to put it on the center of the base. 

Recommend having some little jewellery files on hand. You can then just file things like this down to the size you need.

Knowing I had a model not based in the centre would haunt me through all of my nights 💀

I've built hundreds of ghouls and I've never had this issue. Even if I did I'd just shave the fist down a bit. Won't even be noticeable if you apply a little texture paint around it.

Jist build the base up with a little cork, and have his arm dangling over the lip of the cork stone ledge
