I find it hard to give a useful response to questions like this.
Technically, the images you posted are just fine. They display good craftsmanship, knowledge of the tools, color, geometry, a good sense of visual flow, metaphor, perhaps a subliminal acknowledgment of earlier, vaguely similar work and styles, etc.
The problem for me is once someone gets to this very competent level of their art, IMHO, the real issue becomes one of intent and success at achieving that intent.
In your case, this is something we don't know. In contrast, in the case of famous artists, we have writings, interviews, their entire oeuvre, etc. to refer to. For example, at the most basic level, we don't know if some of these images were intended to be commercial (eg, for advertisements), a commissioned portrait (a possibility in the case of the 1st), a fantasy construct, part of series you are doing called "speckles" (just kidding), or nothing more than an assignment for a class to simply demonstrate your technical prowess to pass a particular course.
Personally, in the absence of all other info, I like the 1st one the best, but that says more about my preference for realistic / representational work than it says about you. Let us know more about the background and intent of these and perhaps a conversation will develop.
Best regards,
