I do not mean to offend you, I am just being 100% honest and not attempting to sugarcoat anything. This is also my personal opinion, although I believe that most artists here will agree with me.
1). You used to renders, which by extension means two focal points. That's not good, because they are competing for attention. It also fills out the signature so it doesn't allow for any effects.
2). There's no point in rendering the players yourself, quite honestly, it's a waste of time. There are plenty of renders out there that could save you an hour or two, and if you find out that you did something wrong in the beginning, good luck, because you're going to have a tough time fixing it.
3). The white dots, quite honestly, at this point, do nothing except obstruct the signature. It does not help people understand the hustle and flow, although putting them on overlay or a different blending mode might make them less obvious and more subtle.
4). My last part that you were offended by wasn't meant to be offensive, but what you're currently doing resembles more of a poster that you might hang in your room and less of a tag. Practicing graphics with items such as guitars, or computer-rendered characters such as a borderland character or so will only help you understand basics of tag design, including blending and color selection. Tutorials would guide you while you do so.
Lastly, I appreciate that you put a lot of time into it, but you have to put time into every good tag you want to make.
