Roadblock is just perfection! Wish Sideshow gave us that.
For having a very plain looking design Jinx looks accurate, good choice for the head sculpt. The shoes look like ballet slippers, might be easier to just make them.
Did you paint the dragon emblem on her tunic? It looks really good. I tried the decal route on one I put together a few years ago, and it looks OK, but I was never happy with the decal residue I could still see around the edges. Yours looks very nice.
