You can control the detailing, but it's a bit tricky to work with at first... you can also get a larger render, but you have to go about it in a slightly different way... you would have to set it up to animate the single frame you want, and the size you want it to be, then animate it using the sketch settings... I'm not in front of my computer at home, so I can't give you the exact steps to take to do this, but it can be done. Also, do a search in freestuff, there were a few free sketch render settings available at one point... I want to say they were by Don Albert? But I'm not sure about the name... there are also a few sets avaible to buy over at bbay.
