1)I'm sitting at around 450 flashcards on anki, and I was thinking of dissecting kanji that are used in all the words across all those cards and make a separate card for them each.

2)I've been using 1 card format throughout: basic. Is this a bad idea?

3)I wanted to put a picture so I could remember for each one (except for about a 100 that are the alphabet, so for about 300 cards) but that seems.....difficult, to say the least.

4)Ideal study settings? I want to do more than the default, and I think I already tinkered with them, even though I don't get it fully.

5)I want to get my deck checked as I'm afraid of typos, mistakes or other problems (bad flashcard design...etc).

EDIT:6)Should I have example sentences with my vocab/particles/phrases? And example card names that use X kanji(half of what I'm learning is directed at JP trading cards)?
