First Charcter Try in ZBrush

Hey guys I am new to ZBrush and ZBrushCentral. I’ve been told this is a great place for advice, tip, and techniques on how to sharpen your skills. So here it goes… This is my first Character. I got the idea off of a tutorial I was doing, then took the character in my own direction. I like how it came out, but I would’ve like the pants to have more texture and look realistic. I polypainted the material, but I’m sure there is a better way to make it look more realistic. Any advice or tips you guys can give me?
