Making a MArio/WArio themed tileset Options

[heartlessmushroo...]

For my current project I'd like to make the tilesets for The Mushroom Kingdsom and Diamnond City in the style of the MArio and Luigi games. I've tried to rip from Ithe sprites of Bowser's Inside story but they are incredibly hard to rip and in the end they didnt look as good as I hoped when used in the XP engine.
. Could you guys give me any advice or help on how to make them or at least rip them properly please?
