first one, would have to be too dark and a lack of effects on the left side to add flow.
second one doesn't look much, just a slap on render with text.
third is the best out of the three, but sorry, i hate how you extended the tag for the render, and also it's over-contrasted in the actual tag.
Keep it up, and you'll get back into your old groove, which i haven't seen, but i have a feeling you can be really good soon.
