I’d say you’re off to a great start, Kyle! I like that you’ve honed in on an elongated face – a recognizable feature of Benedict. And I like Matt’s feedback – I second his notes.
Here’s some annotations over your image:

Note the distinct slant of Benedict’s eyes and brow. Compared to yours which are fairly straight horizontally. Also the upside-down triangular shape of his nose. My eye immediately went to these features for exaggeration.
Also he’s got distinct but short laugh lines straight down the sides of his nostrils, which is a feature missing from your sculpt. Also the lower lip is a distinct feature on Benedict that isn’t formed with your current WIP.
I’m looking forward to seeing how you progress with this one – Keep up the good work!
