Ohoho, for this one, just a little detail to bring up: when you have a certain area unfocused (like the foreground) and another close to it focused (the character), it implies a short-ranged depth of field.
In other words, since the foreground looks blurred and the character doesn't, the background should be unfocused as well, because a photographic lens sets a round area where things stay focused and leave the rest blurred.
That, of course, talking of real photography, but with a brush, every combination of focus is possible, although it might look odd for more trained eyes.
