Nice shots!
I think there are a few things that could be improved on though. Have you thought of trying a tilt-shift? or possibly a lensbaby? I think these would open more compositional technique.
Seven - Good, but the oof lights draw too much attention to the RHS and pull away from the focal point with nothing to balance the image. I'd have liked to see a triangle here with the eye moving between a primary, secondary, and tertiary focal points keeping the eye in the image.
Barebones - Nice, but I think needs focus stacked to really have impact. The oof nearest the camera pull too much attention and kinda look a bit careless. In a carefully composed image I'm looking for the eye to be led in.
Cattail - Strong composition here, but I'd burn the background down by 1/3 of a stop ir so, currently the whites compete a bit too much with the cattail to return the eye.
MIL - A difficult one. Compositionally this is pulling my eye towards the centre of the frame, but there is nothing there. Thereis a nice curve to the DOF, with the in focus flowers, but this is where I think a DOF that's a little askew could have led the eye to the bright background bokeh if it had been slightly shifted.
Overall these are really very good, but IMO with slight compositional tweeks could be exellent or outstanding.
