Do you think I'm a fairly good photographer for a thirteen year old?

I’m 13 and my passion is photography. I have a Nikon Coolpix L120 right now and it’s my baby. I take a lot of nature macros mostly because that’s really all I have to shoot. I have an account on a website called View bug where I put my best photos and can enter them in contests and things. So, if you would please look at my pictures and give me some constructive criticism it would be greatly appreciated! Here is the link to my View bug account:
