Filler for pottery

[TrevL]

I have a stylised pottery piece of a man and woman clasping hands, (present from Mexico), which my toddler grandson knocked over, resulting in the man being decapitated at the waist.
I've stuck it back together with superglue, and it all lines up nicely.  However, there are some small shards missing so could do with a bit of filler, what would you recommend please?

Try Milliput Super-fine white.
