PCB Critique
Currently that's a pretty poor layout. Be prepared to give it a fair few more goes before you will get much positive feedback. This version has poor grounding, poor layout and...

Current Limiting Diode (CLD)
36V at 3A = 108W This project certainly is not simple, the fact that you are suggesting using current limiting diodes (and from what I can gather a non-isolated approach) for this...
