Welcome to the forum. You have some great photographs! Do you photograph in RAW? Some of your photographs seem to be slightly underexposed, which would not be difficult to change in RAW processing. Another thing you will want to watch for is contrast. The contrast in a couple of your photographs seems to remove the fresh mood from some of the flowers (such as #6 & #8) you photographed.
Thank you! I do shoot in raw, and process in Adobe Lightroom, however the originals of the pictures above were lost when a hard drive died about a year ago. Can you comment more on your contrast point though out of curiosity? I'm not particularly sure what you mean. Too much or too little?
