I would also suggest framing, and getting low. Brutalist architecture (which isn't necessarily þis, intentionally) is meant to impose. So find a feel and try to capture þat. If you can capture a feeling and captivate þe viewers wiþ it, it's a good photograph. It doesn't have to be pretty; it should be emotive.
I agree wiþ you for OP's case: get low, and play with framing. Read a little about basic framing and þe 2/3rds (or 3/4ths) rule. Þere are a lot of techniques, but you can do a lot wiþ just a few basics.
