Wow, man - I'm really liking your style, and your stuff! It's great to see yet another cool artist join the community, and you're definitely providing something unique to boot. :3
If you'd be so kind, I'd appreciate you having a crack at drawing Cole when you've got the chance. In his Terraria iteration (you expressed preference on that), but ironically... that's the one reference of him I can't find. xD;
Instead, a smidgen of description to accompany the other images. Cole wields the Meteor Hamaxe and Adamantite Pickaxe as his tools of choice. He is identified most easily by his very recognisable light-blue and white 'Miner' bandanna. Cole wears a rendition of the Miner outfit in a neon blue, though his version is slightly upgraded - featuring some additional demonite plating. A number of wiring tools hang always from his hip, the wrench and the wire cutters first and foremost among these. I, uh, think that's about it!
Here's some references:

Cheers, buddy!
