Peter Reinharts Sicilian Bread

I tried this bread around four times, 2nd time the bread had amazing flavor.. this time it was good, had a good crust but not the color I want. It thought I wasn't baking it enough but the bread just started to get browner and it didn't come out the way in Reinharts photo of it.

I'm using a electric oven, with stone but its a thin one and using steam. their was a good crust on the bread but the color and texture wasn't there.. there are alittle spots on the final dough.. could the dough be too dry?
