I was thinking about how Oda's drawing stying has evolved as one piece has progressed. I'm sure everyone has noticed how his characters have gone from looking very child like, with a very roundish style to them to hardlined adults. My question is, does anyone feel that there is something more to this than a simple style change? Has Oda ever said way is SBS? Does anyone think it is significant to the plot of the story, or do you feel it is irrelevant?
Personally I feel that the change could represent the seriousness of the characters. In the very beginning as they all start their journey they are still kids and have somewhat less serious attitudes. But now in Water 7 and Enis lobby the stakes are higher, they've become more mature and strong looking as declare war on the World Government. Perhaps it means nothing, but I just thought it was interesting, and I am curious if others have opinions on the subject.
