3 - This seems either out of focus or a little blurry. The focus on the stem/leaves seems a fraction sharper so could be focal issues. The saturation/contrast also seems to be 'blown', losing detail in the petals - this could be exaggerated by the use of 'neat image' or such, but apologies in advance if wrong. Overall there is no 'depth' to this shot (especially against the black background) and very little definition, in my opinion. The thin frame, including color choice, works quite well. Might seem minor, but your title with a " ' " or a "g", would be better.
Well, this is the 3rd flower with a black background. I said it twice before, I just dont feel like these make good images.
The exposure on the petals are a bit over exposed, there is no critical focus anywere in the image. I would also crop to make a better composition, because I dont think this works well.
