Hand Critique and Suggestions

Dalwocket

So here's a link to a hand I've been working on: https://sketchfab.com/models/b8f118666ac34c5291cac3470a89d73c

I'm not sure what exactly needs to be changed and tweaked, but I think something is off. (Heck, I'm awefully sure I've got something off )

Also, anyone know how to get the sketchfab thing to work? My blue little button with the box doesn't seem to do anything.

Not sure how to get it to work but my critique would be to maybe try and get a more consistent edgeflow. You have a few spots that have really large/long poly's next to really small ones.

There is not too much to comment on, some of the fingers seems too thick and the palms polys seems a bit inconstant.
