Looks good! I'm looking forward to something more substantial added to this character.
I like the reflection of the fire in his eyes, I like the warmth of the lighting.
I don't like that the only ambient movement is subtle breathing, pipe-moving, and blinking. I wish he was doing something else that a normal person would do at a campfire.
...For example, its raining...is he cold? Is he trying to stay more dry? He's just kinda dead-eyed as he stares into the fire. Though I suppose that lends credit to the "Weary" in the title...
Also, I found myself staring at the smooth, undisturbed pillar of smoke coming off of his pipe. Not only did I begin thinking of the rain interfering with the bowl, but the smoke didn't look natural. It seemed completely undisturbed by the rain, and the solidity of the grey didn't seem right.
Might I recommend you kinda play a bit of a motion trick on us with the smoke. Instead of a pillar, think of the smoke as a tiny, white/gray flame flickering out like a tongue just inches out of the bowl...but only occasionally.
Look at tobacco pipes of similar nature and watch with great attention to detail on how that smoke reacts. The reality in how it behaves is a beauty that you can incorporate into future animations.
