It's actually kind of funny that you mention that. As it so happens, I have been looking for a theme idea to use so I could record a number of videos specific to making the different sections of a 3ds theme (folder icons, icon borders, etc.) as more "in-depth" guides. Unfortunately, you weren't the original one to give the idea.
As one who regularly has to keep checking 3dsthem.es for new themes that strikes my fancy, I happened upon a
Bakemonogatari theme that Flamespeedster posted. That theme is actually in my Theme of the Week pool, so I won't say anything about it beyond "some things struck my fancy, and some things didn't." I did some preliminary image editing to see if I really wanted to do that, and said no. Then you happened to post about a bakemonogatari theme, and I was chatting about the bakemonogatari theme in IRC, and I did a little more editing to show what I didn't want to deal with in order to make the theme.
While editing, I realized I could reuse the method I did for the Hatsune Miku theme with some minor tweaking to get a scrolling background...though it didn't solve the original issue I had with making the theme. With that said, I actually invested enough time and came up with a plan for how I wanted the top and bottom screens to look, thus I decided I might as well make the theme.
It's not much of a preview as much as it is a shitty half-edited picture, but it pretty much gives away exactly what my theme is going to look and feel like.
I need to finish editing out the rest of Senjougahara's body, magic some of the pole and leaves, do some slight variations on the second plants, fix the gate so they loop (may or may not require some massive witchcraft), and make sure the clouds don't look TOO redundant...and then figure out what I'm going to do about the rest of the theme. The only really regrettable thing is that by rotating the image, I seem to introduced a disgusting quality drop in the image. I might try to find out a way to alleviate that before actually continuing editing the image (this might just be imgur after looking at it again).
I suppose as a tl;dr:
I'm making a bakemonogatari theme. ETA is the same as always, days if not weeks from now.
