That's not Cthulhu.... It's obviously a Illithid from Dungeons & Dragons http://www.wizards.com/dnd/images/dx20050303iw_Sarkt_the_illithid_sorcerer.jpg

Cthulhu isn't dressed and has wings... And is 111001010111 times more badass.

I think I'll stick with my unrealistic, non muscular female anime warriors instead. Not that this lacks any artistic qualities in itself, just my cup of tea.

in short Cartoon > Realism in this case.
