I didn't want to make the bugs, because I thought somebody else was going to do them. Also, yes it would seem weird for me to do them, because I would've made the bugs "item"-sized and not realistic-sized. As in, the bugs would be 16x16 pixels big, not a lot smaller, as would seem more reasonable (1x1, 2x2, 3x3 pixels max). That, AND I would have to make the bases for all of them from scratch (except for the bee and the butterfly).
As for the shields, I used the original sprite bases as well as I could. I know that that makes the Wooden and the iron Shields for
Skyward Sword seem larger than the Sacred Shield. If you would prefer, I'll try to make them fit more using the shield bases (Wooden Shield would use the TMC Small Shield base, Iron Shield the FS1 Shield base)..?
I try to go for either a TMC-styled item, OR the next-best option: a stylized version of an official art piece of that item. I would rather use official sprites as references, but official art is also handy (I am seriously considering making a section for
all the weaponry depicted in the aLttP SNES Nintendo Power Player's Guide - that stuff looks WAAY too good to not sprite!), so best send me in-game sprites or official art in order to help me sprite it better.
The Eldin Ore is on the sheet, right next to the Golden Skull. The Tumbleweed is two to the right of the Eldin Ore.
About the Joy Butterfly: I had actually once used the Joy Butterfly as the base for the Joy Pendant (TWW), but it failed horribly. I just used the resized picture of a real Joy Pendant for the base.
As for the Gratitude Crystal, it looks the exact same as the
Spirit Tracks Star Fragment (but just a different color), so I used the same sprite base. I really can't find anything that would offer a better base for it, and nothing TMC-style.
