None of them really grab my attention, hook my eye or keep me looking.
They are bland to me, there's nothing in them that is interesting to viewers!
And, all the flower ones are out of focus!!?
You should try working a bit on focal points, I'm not sure what kind of camera you're using, but it's a pretty simple task that I'm sure you will
pick up quickly. Pressing the shutter half way down provides focus, you shouldn't move the camera to much after this 1/2 way or it loses focus.
Faster shutter speeds also help produce crisper shots, without the blur or them being out of focus.
You should also work on composition.
The first one is composed excellent, however the rest are all centered, which makes it less appealing to me.
