Headshot mini contest

Credit to Three-MustangStables with their Horse legs plus contest. 
Thought I'd give this a go with headshots rather than legs. 

1 2
3 4

Rules:

1) comment who you think is in the portrait. 
2) only one guess per headshot but you can guess all four. 
3) contest will end when all horses have been guessed correctly. (Or when I want to finish my art xD) 

Prize: Headshot for the winner - in this style. 
N.B: the first person to guess right will win the headshot. 

Hints:
1) He's special to me
2) He protects his daughters
3) He's my favourite of his breed
4) He's my first

RESULTS!

1) Altï - He's special to me because he was my first ever created character (2003) 
- Altï has a Roman nose and and often serious expression of a proud leader. His forelock often sits brushed to the side. 

2) Abyaz - He protects his daughters from the other stallion Pharoah, even though he is generally a very docile stallion.
- Abyaz has a thin and subtle square face. 

3) Inkspill - He's my favourite Beaurever and I was so happy to not only get a slot to him but later own him!
- Inkspill has an Akhal take build. 

4) Apollo - He's my first... pony! Yep, he's the first and so far only pony at AS!
- Apollo is fluffy during winter months and has a bushy mane and tail that's difficult to tame. However he is neatly clipped for the summer show season and so I've given him a bushy eyebrow to show that he's naturally fluffy. 

1) CapNRCubey

3) Three-MustangStables  (how the HELL did you guess that instantly?!)
4) ... nobody guessed this poor boy xD
