Although looking at these pictures now, I guess I'll have to sand down the arms a bit more. They look quite lumpy, with the creases of the original suit sleeves still visible. Thing is, I can't make them too thin as the joints for the elbows and wrists need enough "meat" to not break.
The original hair was really awful. Too white at the bottom and too brown at the top, also thick brown eyebrows. I gave him his salt & pepper hair. Much better, innit? (<-- oh dear, now I even start to SOUND like Alfred...)
