Man, really good icon for Handclaw's old "Goblin Tinker" concept (partially modelled by Jigrael). Too lazy to link, but it's awexome. The hat and everything, man.
Unfortunately, it's *so* well-detailed... I'm afraid it would really stand out compared to other Wc3 icons. But it fits your particular style. Good job; let me know when you've got a simpler, high-contrast version floating around.
