Is that a BB30 shell with an adapter for the Shimano crank? If so...could be yet another BB30 creak from the interference fit interface. However, if it's not that, your most likely culprits are as follows:

With Shimano HT II cranks, a lot of shops screw up the axial pre-load. The part that is commonly referred to as a "dust cap" on the NDS is the pre-tension for the axial loading of the bearings. I see a LOT of shops crank that thing down tight, and then tighten the crank-arm bolts. What this does is side-load the bearings, and over time (a short time if they're heavily side-loaded) they start to creak and tick.

Saddles are a VERY common source of perceived bottom bracket creaks. The saddle moves with your butt with every pedal stroke, and if it's creaky...it carries right down to the bottom bracket.

Otherwise, pedal/cleat interface can be a very common source.
