The Cherry and Whites mustered only three points on their trip to the Ricoh Arena as they lost 23-3 and slipped to ninth in the table.
However, Humphreys is adamant that his team have some positives to take with them back to Kingsholm.
He told reporters: "We just couldn't score. Large parts of our game were good. Our set piece was excellent and it's ironic that the parts we were good at last year fell away today whereas some of the weaker areas were strong.
"We stuck at it and kept working but we didn't kick well enough in the first half. They got into our half on only four occasions with Elliot Daly kicking three super goals and they scored a fantastic try."
Gloucester have now failed to beat Wasps since September 2012.
