Ahh really nice work t-k! Great shading on the base and a good shade of blue too. Works well with the metal
As far as suggestions, I think mine have already been covered. I agree with the uniform size of the left and right buttons (pl/ml and pre/next). That should balance it some. And One other suggestion is to have the eject button on the left so the right isnt as crowded
That's really nice.
The left could have something more,
and I think the pl/ml are too big if you look at it symmetrical to the right.
Maybe you can make the pl/ml the same size as the prev/next and make
another same sized area as the play button on the left, but then with the progress bar in it.
Then make it light up from the center outwards when the song progresses.
