looking for feedback on my retopology of 2 meshes

Hey @yukinoh1989 , nice work! Here are a couple notes:

Try to avoid loops twisting around the model. In this case it’s not the end of the world as it still flows ok, but notice how the highlighted loop starts on the inside of the legs and ends on the outside:

The face looks quite good. The change I would consider making there is using a loop to explicitly define the jaw, because otherwise the flow from the neck to the chin and jawbones is going to be soft and mushy rather than looking like there’s a skeleton under there:

I would also try to avoid junctions and poles in places that are going to twist and deform quite a bit because they tend to collapse or pinch:

Hands are pretty tough, but try to keep the loops from wandering around the model by connecting similar parts together and creating closed loops where possible. In the below example it would be better if the spaces around the middle finger was connected like you already have for the pointer and ring fingers. 

Overall you’re definitely on the right track and this is looking good. Already this is a usable model, but with just a couple tweaks you could take it up another level.  Hope that helps!

Great notes @jlampel,

My only addition to that is across the belly.  At the moment there is quite a lot of spider web going on, It will deform better if it has a more horizontal flow rather than those diagonal spider webs.  (Hope that makes sense)
It’s a similar issue to what Jonathan explained with the neck above.
