So this is my crack at Martha Jones.

Things I am not satisfied with:

• the colour of her jeans, which should be darker - but I could not find a more suitable yarn. Obviously I frequent the wrong shops.
• the colour of her skin: again, too bright; but again, no luck in finding the right yarn.

Her costume is more or less as worn in the majority of series 3, closest I think to 42. The earrings are Smith & Jones (also, they are real silver!).

All in all, I think she turned out rather nice. At least, I hope so.
