I'm not very happy with the paint job, but my next one will be alot smoother.

So I don't think the current plastics give over the general:
'I'm strength 4, AG1 and armour 9 mate, watch out! I'm slow but hit hard!!'
Hence the bigger belly and 'belly armour'.
I think this converted Lizardman looks alot less agile, and bulkier.
