The second one looks more like a tervuren!
Malinois are traditionally bred to work (although there are show lines) and therefore they are not bred for uniformity of look or type as much as for working ability. Other breeds (like gsds and great danes) have been added in and there is a HUGE variation in the size, shape, etc. of individual dogs.
