Fails to boot here. I thought changing characteristics from 0x60500020 to 0xe0500020 would help, but no. :/
This change would make the code section writable.

FileAlignment you use is probably wrong, I think it should be 0x200 not 0x2000 .

Maybe you need to add a data section and fix SizeOfInitializedData too?

It just hangs on a blinking cursor, no idea if it actually started executing anything yet or not, since nothing is printed out.
