I don't know how well learning from a tutorial works--especially for the cutting bits, it helps to be able to ask someone if you're doing it right. But good luck!

Pheasant quills might be a bit small, I don't know. Even (especially) for small writing, you want a bigger quill so the nib end will be fairly flat. Hence goose (traditionally) and turkey (cheap and readily available in craft stores in the US, don't know about other places).
