I have to agree with Steve Reddin. Your technique is fine, absolutely no problem there, but the images are nothing that fascinating/different.
However, you are young (going by the avatar photo) and for all we know you have not been into photography that long. So that maybe you are still in the learning technique phase while looking for your own style and, frankly, if that is the case I see no problem with the images at all. Copying/recreating styles and techniques we've seen is a great way of learning, one a lot of us have gone through.
Tbh, one thing that makes me think this may be the case is the different styles that you are showing us. Usually, photogs who are further along show more consistency in their style. Not to say they don't do different things but there is something about the images that tells us this is so-and-so if you know what I mean.
Last but not least, some of us take longer than others to find our own style. If you're not ready, you're not ready.
