I'd recommend adding "pixel art" to your tags during training. It will remove the "smear filter" appearance (and if you do like that look, you can just not use the tag in generation). You won't get accurate pixel art without extensions made to do that, but it will come a lot closer (and be compatible with those extensions). You'll also likely want an otherwise meaningless trigger (e.g., "D_F_S_S", "dafa77") because your current one risks random daggers/autumn/stumbles appearing.
