Still I have some considerations to say.
If you have problems (I doubt it) use a longer prompting.
Skin failing? skin not purple enough? "purple" is your friend (purple skin, purple, etc.).
Want "classic" comic suit? "classic blue and yellow battle suit" is your friend.
Helmet also can be added with "helmet" or "classic blue and yellow helmet".
Infinity gauntlet is also a subtoken in the case you want to try.
