You made it, you say? If true, I'd say it's at least worth 4k tc. On the other hand, it seems a little copied. You know, enlarged pixels, exact pixel placement, ect. Unless you found this on the internet, I'd say you did a pretty darn good job.
How do you get such detailed mechanic parts, and how do you reflect one half of the image so it matches the other? I can't get anything precise at all. :S
I say its pretty much worth between 10k~20k or more.
Try to be more clean and add better shadings next time.
