Hi Twiggy,
You're a creative lady! I can see a lot there I like. The graphic content hardly worries me. I do have problems with the writing over the image. This makes it a challenge for us to understand the art.
So here's a very gentle opinion, just my own $0.02, not some strict rule we have, just common sense, as I see things: We don't want a barrier between your intent and what we see. Usually we take a picture in one pass of less than a second. If you can let go of the watermarks*, it will be great!
