I gotta agree on the legs, the back ones look good but the front ones are too close together and it almost seems like one of them is missing; it would look much better if the one that's further away from the viewer was a bit behind so that all four legs are perfectly distinguishable in the silhouette. Other than that it's pretty decent.
I think she means the front legs, and the second to the back leg (the paw) the front legs are probably too far (Atleast I think thats what she means, cuz they r fine) and the second back leg (paw) you see it (They are fine, Blue)
