What would be a good figure to use?
 

I plan on making a Marvel Legends custom of this custom Marvel character I'm writing about. Anyone have any ideas about where to start with a base? A good headsculpt? I was thinking down the line maybe when Christmas comes around honestly right around the corner lol I was thinking about buying ML Winter Soldier Black Widow with the longer hair sculpt and repaint it. My character is a young adult in her early twenties. I also want to have a hoodie body for her of some kind. I guess I could get someone who makes custom action figures to do it but yeah anyone have any ideas? Or advice?

Spider-Gwen, with Valkerie's braids?

You could use the hood from Spider-Gwen and if she's more civilian, some Buffy figures from the Deluxe line have good articulation, are young, and could work (hair might be a challenge).

I might be able to help. But your post has no commas and it's a bit difficult for me to read. T V T. Let me get it straight, you want opinions on the head sculpts & clothes accessories for Black Widow?
I have a lot of choices of custom parts, might be able to help you take a pick. But need more insight about this character you're building.
