Speaking in general terms as far the overall hull planking is concerned.
Looking at the 1st image:
The run of each row of planks is constant from top to bottom of the hull. the upper-works (above the waterline) is laid down from stem to stern.
the planking from the water line down, should be a "continuation" of it (again from top to bottom). The waterline is marked on the image but it does not mean that the planking is laid down differently. This can clearly be seen as the plank edges run through the waterline. If the hull is to be fully painted, then as far as the model is concerned, it would not make a difference. If only the very top is painted and everything else is left natural, then, it will look strange.
So, problems( (2 obvious ones) on the model, and again not particular to the bow:
1) The wales are missing in the model. They are an integral part of the planking as they have a purpose. By definition, they are thicker planks: not a second layer added after a first layer has been installed.
2) The planking runs should not stop at the waterline: then another different run below, in a different direction: showing an horizontal line through the hull. If this horizontal line precisely represents the waterline, then it would mean that the planks above the line have been laid down wrong: and it looks like it is the case: the planking should run horizontally from front to back, but should follow a slight vertical curve due to the shape of the hull. Structurally, it would be bad for the integrity of the hull. Basically, the waterline should not be visible by the way the planking is laid down on either side of it: by planks running in a different directions.
If this hull is planked with 2 layer, this would be ok for the first layer. the second layer would need to be more realistic and laid down properly.
There are more issues, but they could be considered secondary as far as the model hull is concerned: again it depends if the hull is going to be fully painted or not. I see that nails have been put in place in the mid section, so I would imagine that this area will not be painted. In this case, yes, there could be some improvements in the way the planking has been laid down.
