Work on colour flow, the pinky redness of the focal really doesn't flow with anything else in the sig, its also very "RIGHT THERE", lol best I could describe it. Also work on some backround flow, it kinda seems like you've got something going on with the white, but then the green stops it, I unno, just my opinion.

Keep trying! And I'm not saying this from thinking I'm an amazing sig maker, I've just seen a couple bajillion XD
