The proportions of the overhead life bar seem a bit off. The summoner name seems to be an okay, easy to read size. The level number in the circle is small to the point that I have a hard time distinguishing between 5 and 6, and 6 and 8 at a glance. The life bar itself, on the other hand, seems ridiculously huge.

I haven't messed around with the HUD scaling yet, but it feels like the scale of the overhead life bar could stand being scaled back to 60-70% of what it is now at the default.

For the level number, I don't know that it actually needs to be any bigger. Perhaps just a font change to make the numbers easier to tell apart?
