From what I see in the last photo, your pieces were too dry when you scored them, of uneven dryness between the pieces, and not enough slip was used between the pieces. AS @sorce says: "Those score lines shouldn't be visible at all, that clay should be homogeneous".

I agree on this point from that photo -also a lack of slip-I just do not see much slip in there.
