Hi,
While I can see how the first seems anthropomorphic, it has a much more aggressive appearance and looks better compared with the second. However, too me, it seems as if in the original Dis, those heavy metallic lines were not necessary "teeth" as it is implied in your creation. I guess you might consider trying to blend in the "teeth" into the background skin of the ship so that way the front of the ship does not resemble a mouth. I can't say much there since I have no idea when it comes to creating new ships like you have done.
You have done a great job remodeling the Dis. If nothing can be done about the front of the ship, I'm sure others will have better ideas than me, or you might just go back with the original front you had, which looked fine as well.
