I think your series #43, and #49-#52 have real potential but are not quite there yet. We need to be able to read "Curtainwalls & Windows Inc." Maybe try two buildings in a grey/silver tone with blue background. I like yellow/gold but may be too busy...perhaps a flatter color for background. I think that too much use of gradation will make logos translate poorly for certain applications, such as embroidered tee shirts and hats. Thanks very much. Nice work.
