Starting on the left side of the large feature just left of Scott, make the big moves up the steep face on increasingly worse holds until just below the lip, where you'll be faced with the last move of the crux: an explosive throw to a rounded jug. This is the hardest single move on the route and for some it will be low percentage and definitely harder if you're short. From here, manage the pump factor before completing several long reaches on rounded edges. Don't fall doing the last big move before clipping the chains as there is quite some distance to the last clipped draw.
This route seems likely on the harder side of 12c when compared to others of a similar grade at the Tunnel
