They aren't all bad. Feral and Siryn's hold up to today. Boomer's outfit is only bad because the coloring. You do that in more muted tones and it would be awesome. Sunspot and Shatterstar are mis-colored in that pic right? Sunsport was red and blue and Shatterstar was white and red? The costumes themselves aren't bad. Cannonball's is good except for the excessive pronouncement of the padding
Rictor's is bizarrely out of date by about 5 years at that point. He looks like a hairband roadie. Warpath is more of a YMCA castoff.
