Hi, I think you are using 6 leds/CC driver by connecting them in series. I could only see 3 CC drivers(wson8 package) on the left side. Why do you need LM7812 regulator instead of switching one? Do you use LM2672 to supply ESP12? Did you check inductor's current capability? They look a little big. As a note: you should think about soldering process, you can place the AL PCB on a heater oven to solder easily plated half holes. I liked your connection type between Aluminium and FR4. Also your 3 layers definition is great. If you can schematic with me i can review your circuit. Also i can review it also in terms of heating, noise etc. I've done similar circuit like yours. I can review your trace widths, component values.. Let's discuss on chat.
