I've browsed some of your art. IN ANY CASE I think you have some potential. By far I will say that this is my favorite out of the bunch.
What I'm going to tell you with honesty is that you have to focus on some of the fundamental skills with art in understanding shape, form, volume, shading, color theory, and all that other stuff and keep practicing from there. Because you certainly have the ideas here and I think you have the dedication for it but you're not at a place where you have a certain level of mastery over your skill set.
And the thing with that is that it takes time, I don't know how old you are or whether or not you might be in high school or at a college level, but I would say take advantage of as many art classes that you can and really study form. But one thing I would encourage you to do is use a sketch book and let your ideas flourish in the mean time and develop a process to get you from point A to point B.
But again, I actually like some of the ideas you have. But it's that sense of fundamental art knowledge and the sense of direction you need to get at a point where you have a sense of mastery with your skills.
