Welcome Half Moons. Happy to see new members posting ! I like the third shot you have here. I'm partial to windows and geometry ;-)
The other two don't do much for me. On the 1st it's the cross-processing. While I like the negative space of the sky using that much of the shot, I'd like to see something of the sky there - a wisp of cloud or haze, some color, etc that may have resulted from standard c-41 processing.
Nonetheless, a nice start with your blackbird !
