what is "looking good" for you?
And what sideview battlers do you need?
For example, Battle Engine Symphony has addons for three different types of sideview sprites - Holder, 8D and one whose name I don't remember. And other sideview battles don't use sprites but simple pictures for sideview battles.
Please give a link to a battler picture that you consider good looking and a link to the sideview battle script you're using, after that we can point you to the correct pictures.
