Theme generally looks good. Wallpaper is nice, but "busy" which is to be expected.

Since you have the source graphic for the wallpaper, could you also add the following sizes please?

• background_320x240.png
• background_480x320.png

Also. a trailing newline for THEMES/Secret_Garden_KR/theme.yml, which will get rid of this complaint from git / GitHub:

I gave the screenshots a little upgrade and just pushed the update 🙂
Let me know if anything else needs tweaking. Thanks!

Can you add the following background images/sizes also please? They are optional, but better to add them now. Then it should be right to merge.

• background_320x240.png
• background_480x320.png

[siyeongjang]

Added the optional background_320x240.png and background_480x320.png as requested.
Let me know if there's anything else — thanks again for the feedback! 🙌
