It's good .. trust me it's good.

What you should be focusing on(if you pardon the pun) is the metering, as already mentioned.
There's no prize given simply because you shot in full manual mode.
You don't become the elite of the elite simply because you shoot in manual mode.

Manual mode has a purpose ... and it has nothing to do with teaching the operator a good lesson.

What's far more important is to understand the metering, understand how the metering types all work, working out which one is best suited(either to your workflow, or preference) and going on from there.
Read the lighting requirement of the scene ahead of taking the exposure, so that the exposure is about as good as you can get from the camera.

Good to see that Av mode is working OK for 'ya so far.
