Hi Dominic
Vivid - I'm pleased that you kept the shadows as with the white background there would have been danger of the plant 'floating'.
Good choice.
Large - As Allan says, it works on two levels, so good job and well taken.
Architecture - Difficult... I prefer the building in #2, it's the more interesting of the two in my view, but the blown sky lets it down. I wonder if there is opportunity for some creative editing.
