In my opinion the HP bar needs to be cleaned up a little, the actual HP bar looks awesome and is really clean but there are these useless bits attached to the HP bar that do nothing apart from clog up the game screen. The bits I'm referring to is the semi-transparent section under the HP bar (serves no purpose and actually gets in the way during game play) and to the right of the HP bar that spans the width of the rest of the screen and covers the score and percentage (yet again, serves no purpose and clogs up the game screen). The part that covers up the score and percentage actually forces the user to use the pie chart option and makes the HP bar incompatible with other score and percentage fonts other than the ones provided in the skin itself.
EDIT: Oh and also I noticed that the end of the HP bar isn't coloured like the rest of the HP bar, don't get me wrong this skin looks really nice and I'm nit picking but it's a fault none the less.
