That's a really nice logo! I especially like the grading on the 1000x1000 version - and the two spaces in the square! A nice touch.
On the topic of Logo Contest, I announced the winners of the LFN logo contest, you participated in. There's a surprise for every serious entry (including yours). So hopefully you'll check it out. I have also posted the part 2 as promised.
Thank you a lot @rawbinhutt!! I am going to surely participate in the second part too. :)
