Glowing player buttons

Morgan's work (the level of detail, subtlety of shadows and highlights, the overall finesse) is amazing!

Suddenly, I imagined the same UI, with one more possibility: the buttons glowing subtly (when one of them is active). This is what I came up with. I recreated the UI (all vectors), then added the effect to the buttons. (You can download/view the editable ui-miro-glowing.fw.png file, if you like. ]

I did the experiment for pure fun and to try my own skills (I have no intent to publish my work elsewhere). :-)
