i agree with raven about the background but i quite like the white fading lines, its fine what u did with the renders but the bg is just too simple, add some effects black suits it tho so keep it that style
yeah. you can smudge the background. Cos the background is too plain. and the bars.. give them some opacity... like 45% to 50%.... and a sig should not have mroe then 2 texts unless they are real small like 12px.
