The last two are the best, the first one hasn't got much of a focal because it's blended in too much, don't like the background of the second >.< that may just be me though but the last 2 i like. The very last one is the best out of those 2 because of the small blue soft brush just under the render which throws it. With the last one i would remove the text or blend it more and then make a bit more depth on. Nice work though Bud = )
