Full sets might take a while to make them 32x32, and I'd start of course on the ones which already sold the most. The wizard set is rather new and therefore would be adjusted way later.
But if there are specific icons of a set you'd need in a size which does not exist, don't hesitate to contact me and we can find a solution. As it's also easier for me to adjust just a bunch of needed icons, then a complete set, with shadows, outlines and all the versions - it just takes time and I am doing this in my sparetime only :)
