*wolf whistles* Wow, isn't she a pretty Lassie....Good work so far...only thing I cold suggest is mark out the different sections of colored fur....but hey, I've only sketched a bit, not an artist ;)

wow that's really good, there is nothing that I could tell you that would make this look any better. The body shape, the muscle structure, the pose, the expression on the face, it all looks perfect to me but then again i'm no expert.

Keep up the good work ^^

Awesome picture! :) Great for a sketch, can't wait to see it fully finished and inked. :)
