I would say much the same rule applies for Steve as it does Natasha. IF there were unlimited icons. However, perhaps the answer should be: one less than Natasha? (Steve makes some of the prettiest icons, however, I'm hard-pressed to find a truly amazing Nat icon (setting aside the amazingness that is Natasha, period.)

I often think that I should sway more toward stock icons since I can never achieve a fair balance between all my fandoms, but then every time I talk to about a character, I get really frustrated if I don't have an icon for them.

But please tell me you kept your Cassie/Nick icon because that is pm why I added you. I didn't NEED to know anything else about you, but was of course pleased to find we had other fandoms in common as well. (ah! found it, you kept it, excite!)
