A while back I purchased Heresy's "Dr. Hugh," a 28-32mm "not"-version of David Tennant as the Doctor. (No longer available there as far as I can tell.) I like the body of this figure but the face is slightly exaggerated. He fits in nicely with my classic Doctors though.
Warlord Games has two official versions of the 10th Doctor currently available at approximately 38mm scale. This one is resin and was originally created for Gale Force 9's board game but is now available in a pack with the first and fourth doctor. This figure is ok but the face is rough and not a good likeness in my opinion. (I can't bring myself to show a pic of it straight on.)
The best of the three in my opinion is this one, cast in metal, from Warlord Games' "Tenth Doctor & Companions" pack. The pose is pretty static but overall it is a very nice figure and a great likeness. I tried to do it justice. (Somehow the photo makes his eyebrows look more intense than they do in reality.)
Finally, I also painted everyone's favorite robot dog, K-9. Great figure and I'm pretty happy with how he turned out. (Also from Warlord Games but as a promotional figure)
That's it for now. I have more Doctor Who-related stuff to paint: companions, Sea Devils, Zygons, etc. but a bunch of other stuff is on my table as well, so stay tuned.
