I have gone this far on retopologizing a game char. I have gone through many resources on how to make the hand topology but all seems to be different depending on the modeller.

I attached a far camera screen to show the edge flow through hands. The other attachments are showing the close up topo of the hand. No triangles so far... I don't have animating experience and planning to learn rigging and animating when i complete this model. Considering my zero experience on animating, could you please show me how to complete this hand model. If you could draw the edges and show me how to complete this part i would be glad. I can't decide where to put my triangles here... I am sorry for the large images, i thought it would be the best in this case to attach them on my message instead of pasting links.
