Hm...if I had to choose, I'd do it without the sketch and add the sketchy looks and effects when you color it over. ^^ That way you can retain a little bit of both in your piccy!~
By the way..your guys anatomy has improved like WHOA xD I especially love the details...gosh you're getting soo good, it's making me jealous LOL

ummmm I thinks you sould do without the sketch.

There, you have my oppion, and they don't come cheep. You can pay me by telling me who this sexy guy is!
just kidding you don't have to tell me..... but it would be nice to know. xD Or you can just say "sush sophia-chan you will find out soon enough" Or I could stop rambling and wasting your time. xD

Okays I'm done now. (wow I really do like to type xD) SEE LOOK AT THAT I CAN'T STOP. xDDDDD *is really done now* wow that was lame.

Hmmm i like the sketch underneath it in some spots, like in the fur on the jacket, but not in other places. >:
Your choice though~

i agree with Sashyfrassy, n the sketch does look a lil bettr

yes, i bet it'll look great when you color it.
