Have you fixed this yet? It looks to me like you have some pretty bad over-extrusion. Your e-steps are only half of the solution for extrusion, you will need to adjust (lower) your extrusion multiplier in whatever slicer you are using. While fixing your over-extrusion will lesson the seam seen in your second photo you can also help with reducing your retraction on layer change slightly until it is no longer as noticeable.
