That's exactly what I was worried about! I did want to put emphasis on color only in Mikasa's mind so that we had something that was much more ... um, /her/ besides her fear of losing family because she hadn't in this and I was concerned about putting TOO MUCH emphasis and making the chapter boring (a reason for which I almost rewrote that chapter) and now I know I wasn't a crazy person! XD
The new writing style was supposed to be more poetic and long-winded -- going into further detail than people really needed. I wanted to try it out because I've recently been reading books like this and I found it very attractive -- it allowed the author to paint without even picking up a paint brush and I admired that. So, yes, I know it's long-winded, I just hope it's not ... /too/ long xD. Usually, my writing is much more pithy.
Confusing? Ah, yes, that was a concern as well. Multiple times I believe I attempted to use a metaphor to show what was actually happening and I was really hoping people would get it but maybe it just came out like a jumble of words instead of narrative.
Something I also wonder about is if I'm making the characters unique enough and true to themselves. I have a habit of making my characters cardboard cut-outs and one-dimensional beings just to fill the holes of the plot so I was hoping to avoid that this time lol. I hope readers caught on to the differences of Mikasa and Eren's characters when their reactions to the letters were much different (Eren punched it away and Mikasa took a much less aggressive approach).
So thank you very much! This was actually really helpful! I will keep this in mind!
