Coming along nicely.Perhaps drop the lineart behind the paint layer and drop its opacity to like 10-20% at most. So you can see it behind the sketch, but barely. It will give it a nice painterly aesthetic.
I agree with Jon. Maybe use the "Lock Transparent Pixels" option to then paint over your lineart to an appropriat colour. It can look great :)http://browse.deviantart.com/?qh=§ion=&global=1&q=pepper#/d2ht4efHere for example, note the change in tone say, between her shoulder and eyes.
Didn't even know about this Lock Transparent Pixels tool!! :D Will check that out, cheers dude.
The only thing to know about the lock transparent pixels option is that it requires your linework to be on a layer above your background, otherwise it won't work
