I chose to do, what I feel is Cyclops most iconic costume, the dark blue, and yellow, with the red belt, and thicker visor. With the belt I decided to go with the John Byrne version, wide, with a red 'X', instead of a yellow one. Different artists would change not only the belt, but the style of the boots. For me it had to be the costume worn by Cyclops in the 'Dark Phoenix Saga'.
I used the Eaglemoss Cyclops for the base, which involved some minor filing away of the raised lines, and Milliput added for the boots, belt and visor. The visor was incredibly tricky to do, but I didn't want to just paint the thin existing one gold, it wouldn't look right. The big chunky visor was also iconic of the 80's version.
Here's a picture of Cyclops and Nightcrawler, both in their 80's costumes.
Now I can concentrate on the Oracle commission, and the Death-Stalker for my DD collection.
I do have a couple of other commissions to do, but getting hold of base figurines for them isn't easy, it's amazing what price people will pay for a Classic Marvel Figurine Collection Figurine.
