I'll be totally honest with you mate, if this is just a hobby to you then more power to you but you really can't blame people for brushing this sort of stuff aside. Whether you like it or not, it's blatant tracing, and it doesn't matter how many fancy terms you try to throw in front of it, it's still tracing to a tee.
I guess it really depends on whether you just like doing this because it's fun for you or if you actually want to grow as an artist, because this is definitely not the way to do it. And if you're just doing this sort of stuff to please yourself, then maybe you should just keep this sort of stuff to yourself, and show anyone that you think might want to see them. You can't really defend this as art though.
