As Ral said no, the key is to start with smaller easier parts and build your skills up like a handplate. Practice makes perfect. Just keep at it and you'll eventually get it. Protip: Don't rush, one step at a time is key to the HD pieces. If you try to cut corners or do any of it quickly you're going to screw it up. They'll save you a lot of time in the smoothing/detailing stages.
