Hi I'm ShareYourHead!
(Share for short)
I am a long time minecrafter, and have been making skins pretty much since I started the game (just for myself and friends, and when I'm bored). Anyway, you can see my skins
here on skindex. Eventually I moved on to resource packs, and quickly found myself on the technical side of things rather than just making textures (ie remodelling blocks).
I don't usually do super detailed models, just special things involving blockstates, cullface, stuff like that. If you ever have a question about such things don't hesitate to ask. If I don't respond don't take it personally, I just tend to have like a week each month where I get on frequently that's all.
All my packs are fully functional without optifine.
