Good job,
The overall shape looks great.
Are you using a mouse or pen and tablet to sculpt?
It is harder to keep a steady hand with a mouse.
You could go over it with the smooth brush.
This would be my advice,
Use DYNTOPO with low detail size and subdivide edges, keep the strength fairly low, keep an eye on the brush radius and zoom in close around the detailed areas.

You will probably need to tighten up the creases after.
Hope this helps
