Hello there and thanks for posting your photos. Its such a pleasure to share with fellow photography enthusiasts...its infectious.
My humble opinions on your photos...I dislike your borders, actually i believe that if you are going to take photographs then they have to be the highlight and nothing should take away from the actual photograph. The only one that i liked was the 3rd border, only because it was minimalist and didn't distract from the photograph. Please just take this as constructive criticism.
About the photographs, i liked the first and third ones but the second could have benefited from you including the whole leaf as opposed to cropping out the edges.
