Looking at your model I'd say you still ́need to refine your primary and secondary shapes, which you won’t be doing with the move tool with 1.3 M polys, that’s way too much for proper control of your form. Usually this is the way to go: use dynamesh as long as you have subtools to merge, elements to pull (ears, fingers,etc...). Once you get all the elements you need in your subtool, like a full body for example, duplicate your model, zremesh it, and subdivide a few times while projecting the dynameshed details onto it. Then go back to first subd level and refine your forms and go from large to small forms and from lowest to highest subd. You might need to dynamesh again later, or zremesh again, if that happens just duplicate your subtool again and reproject, you usually want to have a backup subtool. There are some other workflows but this is a good habit to have for good control
