I have some ideas for how the weeping angels could be improved.
1: Instead of them just moving very fast when the player is not looking, i suggest that they simply teleport (I say this because when you are morphed as a 1x1x1 mob you can see them moving if you look away from them and then look down).

2: The textures should have the Alex (New female skin in 1.8) skin, just grayed out like the current Steve skin the angels have (But with a robe of course).

3: Baby angels should have a baby angel skin (Since there is an episode that shows the baby angels with a different body then the normal angels), and maybe a different model.

1 will not be implement. Here is why. A) that's a bug I will need to look into after morph updates B) actual angels just move very quickly. If they always teleported, then statues wouldn't move, they would appear.
2&3) yeah, something to look into. I am not the best at textures and modeling

Todo, label this issue....

I can make the new female texture for the current angel, and the new texture and model for the baby angel.

I cannot garruntee i will use them, but go for it

How do i contact you with the model? do you have a Player.me page?

I do in fact. https://player.me/thetemportalist
