I'll rate the third one Brushing- Excellent. I can't find anything wrong with it. Colour- Great. Maybe a bit bright though. Render- Kinda dark on the right side of it. Text- i love how you use the same text over and over again. It's like your calling card. overall- 9.5/10. VERY nice sig.
top, dont like the brushing/colors of the bg. Nor the text. 5/10 Bottom, simple motion blurs but it looks good, get some better text. 6.5/10
1st: render is overused, the text is kinda plain, but the brushing is alright. overall its just a little boring. 6/10 2nd: very nice brushing, but again i dont like the text. 8.5/10
7/10 hard to tell what the render is, and the tect could eb blended a little better. the brshing is great tho
