Agreed about the joystick dong. 
I would also add a bit of colour to batman, perhaps using some of the darker blue as a mid-tone for batman's shading. This might help sell the "sheen" of batman's suit. It just seems that Batman is so monochromatic, compared to Supe.
Also, I'm not too keen on Supe's blank face...where as Batman's has some slight definition.
If you squint (classic painter's litmus test) while looking at the image, this will give you a good sense of the space composition...defining the negative/positive space usage. Currently, you've got Batman "anchored" to the left frame of the CP, and this empty stark-white space near the middle. Perhaps moving Batman closer to the center and putting more "flair" upwards to embellish the cape could help with balancing out the negative/positive spacing.
It's a cool concept, keep going! 
the think is i like the abstrat thing... i think it looks nice on a control pannel i'm just htinking how to make it look more professional, maybe a little graphics around the joystick and buttons
No, you're misinterpreting what I was saying. I wasn't suggesting to make it not abstract anymore. I'm saying you have an off-balanced image, in the style and the composition.
1. One side is colour, one side is monochromatic.
2. One side has more definition in the details (face), the other is more simplistic.
3. Batman is anchored to the side, while Superman isn't. This makes the image look even more like it's weighted to one side, with the combination of #1 - 2.
Making art look professional isn't about adding more more more graphics, it's about communicating a style that is cohesive and consistent with the theme. Staying within those "rules" you created for yourself, and your vision.
what do you think about it ? came out nice ?
how can i improve it (i thought if anyone will have ideas it's you guys) ?
Like it or leave it, it's up to you. But if I were doing that art, the above comments is what I'd fix to get closer to a professional job.
