Good for pixel art. But not Bowser on steroids by any stretch, he always looks like that. Except with more muscle. I saw the Mario Bros. on LSD and thought "that's not LSD, that's just making them thin and slightly buff".
If you meant steroids as in "high on awesome", no, nuh-uh. Not close.
Although I was always curious about that green round thing between his eyebrows. Never understood why he has that bump there.
