The hearts are two dark. At first, I didn't even notice they were there. Next, the buttons are really kind of pillow shaded, so you should try and improve that. If you can't get it looking like the TP HUD, then made it different and unique - there's no consequence to that!
Apart from that, it's pretty good... let's see... the shadow under Link is a little too solid. Making it semi-transparent would be good... and, the door there doesn't seem to be very round.
The rupee counter doesn't have very good shading.
Then, apart from that, it's brilliant.
