My first attempt at a warmachine. the moral of the story is this: "Make sure you've removed all the mould lines, and don't say 'Ah, to hell with it - it's already primed.'"
Your comments must be refering to the mold lines on the wheels? Anyway, I really like the way you painted the wood. There are a few spots where it looks like the metalic paint bleeds into the wood on the top metal connectors parts. I also think the cannon barrel is a bit too dark. Maybe drybrush some dark grey over the fancy raised areas on the barrel. Overall a great cannon and I like the granite colored ground it stands on.
