As sculpts I've never been a fan of these; the big heads and big hands. Though that's not really a criticism of the technique of the sculptor, more of the stylistic choice (which seems to have been in fashion back when these were released) as the execution of detail is very well done, the mounted figure is a particularly fine piece of work. As the Cid says, they have lots of character.
The painting is just right for these figures, not too fussy, and clearly brings out the detail of the sculpts. The face on the last guy is great.
