I think that #1 and #2 are a little soft on the eyes, also a shame that you have cut off the paws and tails in each. If #1 is a crop, I think it's a little tight and some breathing space would make it more comfortable, as well as also giving it the space to look into. #3 looks sharp, but shame it's not looking at you.
They're cute things, I'm always a sucker for a meerkat.
Hope that helps.
