And this is finally done!
I'm quite satisfied of the result, I like the bush of broom in the corner ^^
And I've used the new brush for do this and I've also changed the color of the outlines, and I have to say I like the effect.
I'm quite proud of Eidan's body (I'm sure he is very porud of his abdominals XD)

for who don't know my centaurs they are:
-Eidan, chesnut
-Echo, gray mare
-Meeka, chesnut filly (on the chest of Echo. Daughter of Echo and Eidan)
-Tory, gray colt (on the side of Eidan. Son of Echo and Eidan)

-Raegan, black dappled
-Allister, buckskin
-Daaron, black colt (son of Allister and Raegan)
-Piper, black splash (daughter of Allister and Raegan)

Here Echo have just gave birth two twins (Meeka and Tory) and she is really tired poor dear. Allister and Eidan have helped to give birth.
Daaron already loves his new little cousin <3
