imo, don't make it a heart, it looks kinda tacky.

 i really like the second as one where you could just fade it out or the third with a bit more neck added on to the mother girraffe.

My favorite is the second. Though they can be intertwined by a skilled artist to capture the essence of more than one, if you like different features of different photos.

And I don't know if this helps any, but when I saw the second photo, the first thing I thought of was a backpiece where the mother is coming from the left shoulder and the child from the right hip, surrounded by some sort of scenic background.

2 would be great for a forearm piece, but 3 seems much better for the leg.

I really like the second one :) I think it'd translate well on the skin. 

##2

i vote for two!!! its so pretty. great tattoo idea 

I vote for #2, its cute. I really like your idea too

Thanks for all the input, guys. I'm probably gunna end up getting the 2nd picture. I still have to put some thought into it. 

I like the second one best, because I portray that the mother is always watching down on her baby. Helping them keep there head up no matter what. Something along those lines. Also, it shows more of their bodies. Necks, in general.

 i like 2.

 Number three. =D

 I also like the second one best.

i really like the third one best.

 I know this is old and dead, so I will lock it after I post.  But I saw a giraffe pic and thought of you.
