The sky in comparison to the buildings and ground below it seems like it need some more shades of blue in it and the sky usually blends with the scenery and this isn't so in this picture. The tops of the buildings look straight black and the sky is blue. I believe it should mix together to some degree. Also, The lights seem a bit too bright in some areas where the light and the dark should have more blending like more stuff in between the bright parts and the dark ones if you know what I mean.
I really didn't feel like I should write a critique here, but when I read that previous critique, I decided to do it.
This is how I see this drawing:
I think your pic gives back that "I'm walking alone in the town" feeling perfectly, the lights and the contrast makes it a little creepy but still beautiful. The positive side of using ball point pens is that you can make a very detailed drawnig, and I think the details on this drawing are enough, but still not too much, this is because I gave five stars on the vision.
I'm really curious, please tell me how many pens did you use to draw this? And how many different colors?
(Excuse me, I know my english is not perfect, I'm hungarian. Did you know that the man who invented the ballpoint pen was hungarian too?)
And here I thought that my twenty-nine cent Bic pen was little more than useless. I'll never look at a ballpoint pen the same way again. It takes a talent that I do not possess to create without the security of an eraser to back me up. Bravo!
