You don't know who the newstars are or you're looking for a specific set?
New Star/Tiny Model/Sweet Model, etc. is a studio that has a bunch of websites dedicated to individual models and they are updated weekly. They've been in business for decades now.
Go to tiny-modelnews.com for their main site, it links to the individual model sites from there. For most of them you need to navigate to the "preview" section for some free pics, or pay a subscription fee and get full access for a month.
