i dont particurly like either of them, mramas looks like a grumpy old man with round eyes, while michos reminds me too much of one of my older tribal heads, which i was never a fan of...
but i chose mrama. his covers alot more of the artistic type bases compared to michos.
he used tribals in a figurative way, and incorporated demon colours to sort of frame the shaman, and separate it from the radioactive. Rad and shaman dont blend too well together and i think it was necesary to frame it like so
i think the main thing that did it for me though, was that mramas looked like it had a plan, more organised and thought out
