Shovel(couldn't find the number)

I have made the following parts from that list:
Elytra Wing
Netherite Helmet
Trident
Shovel

I don't know where to send them, so just tell me where, and I'll send them there.
(also, something I'd like to add: if you could add the seams stuff and other texture things for a lot of the items already in Mecabricks, that would be great(or, if at the very least, you supplied us with the font base for it, so that we can do it ourselves)
I also made an improved texture for the Sheep that can be put onto any color.
