Martin,
As Mike mentioned, you've been here less than a month and very few images. The images you do have seem to me, to be dark and you might have a bright monitor or you might just like dark images. Many of your images are probably more "snapshots" than art and that is one reason for your lack of attention here. Not to mention there are thousands of professional photographers here,that you are competing with.
Having dark or blurry images,just to have "inventory" doesn't help you and can in fact hurt your sales,so keep that in mind.
Now, keywords! The only way people will see you,other than you directing them,friends,family, is through searches so ALL your keywords are very important and should be exact,example: the first image you have is the "Wasp Pollenating", which is actually a Honeybee,not a wasp. So here's what happens, anyone actually looking for an image of a wasp,will see your honeybee and not buy it, but more importantly, anyone looking for a honeybee image won't ever see your image,since the keyword "honeybee" isn't in your list of keywords! Further, it seems that you can spell "pollenating" as you did and also "pollinating", with an "i", so that should be added also. The name of the flower will help too.
Hope this helps,good luck!
Rich
