HA! I had to redo a sculpt over 4 times due to the same reason lol. But each time i had to redo it, i was much faster at sculpting the object. This new one actually looks better than your first one.
Try a spray brush with .8 or more displacement and a really good skin alpha and yoou should get some wonderful results for skin on this model. Our next project is all about dinosaurs so ive been practicing in my off time with skin and scales.
KEEP GOING!!!
