you wont notice a difference.

and go ahead and draw a quick background.... like its outlines... and then you can create a character based upon the door size you created. then just stick to that style and BAM... done.

It mainly depends on the game's colour depth and the computer's power (yep it actually depends on the minimum specs of the computers which run your game).

Normally, if it's a 256 or hi-colour game, I think most computers nowadays could probably handle them well, even with large and extensive sprites in higher res.
But with 32-bit true-colour game, if you use high res. and/or large/extensive sprites, it would rather, depends on the computers.
