Entry #16: Logo works well. the text (name) is bold and clear so it can be read on it's own and stand out and the symbol works well. Variations of the logo symbol would be good and may be a play on the colours on the gardome as a plain green.
entry #21, #22 & #23: Look a little foriegn with serif above the "o", good idea, but #16 & #15 seems a lot better. With #16 being my favourite as that green works a lot better. what about an orange shadow for the house? and or just a plain green "gardome"?
