rebus - ASCII Puzzler 2: Arrows Depicting Movement, Things, or Pointing Out Objects

This is a sequel to ASCII Puzzler 1: Part 1 and a prequel to ASCII Puzzler 3: The Trees and https://puzzling.stackexchange.com/questions/32439/ascii-puzzler-4-not-a-rebus.

Here is the second rebus I have for you to figure out:

 V

---        O <---
 B --|--> -|-
---        /\
 ^
 |

Here is another rebus I made. The main theme of this is arrows.

Hint 1: (if you reword it, this is a major hint)

After that the B was flat.

Hint 2:

A hint to Hint 1: strike out 1, 2, 3, 5.

Answer

I hope this is wrong, but the answer could conceivably just be

B flat minor

on the grounds that

the person depicted is a miner (perhaps that nice round head is actually a miner's helmet) and he's got a flattened B attached to him. (And, er, "miner" and "minor" sound alike and "B flat minor" is a musical key.)

It seems unsatisfactory because

there is nothing in the puzzle that actually indicates that the person is a miner (or, I guess, a minor -- i.e., someone not yet legally adult), and all those arrows (featured so prominently in the title) end up not really signifying anything much

so I hope there's a better solution.
