I think your idea is really good.Execution could be better and i will give you some tips,and you will decide if to agree.
May be you should give a contrast to the whole piece a bit,or just give it some brighter and eye-catching colours,i know industrial means dirty and messy,but the piece lacks something interesting that will catch the eye.May be give bigger contrast to the industrial city background picture,as the whole piece looks monotone and boring.The render looks good,but you should also make it a bit more complicated,add overlayed white layers,and give it some contrast,as the theme sais "He runs faster than Vieira".Well try to show this quality with some brushing and radial or motion blur showing some dynamics.
If you don't like the colour and contrast tip,you should then add more details,like blended pictures of industrial machines,some papers or add more paper/grunge textures.Also add some bigger player pictures may be,so you could bring attention to the player,not the dirty city.About the text-the yellow splash idea is good plus the 'sissoko' text.But the bigger text looks edgy and not so well make,just choose a better font and just erase some parts yourself with different grunge and splash brushes and it will give bigger pleasure as it will look more finished.
Your works recently are good,so if you improve your style it should become popular.Keep working!
