I love the stylized posture and characteristics of this guy.  I'm curious about the stray pixel on his chest, I'm sure it serves a purpose but its a bit distracting. Good job!

re - uploaded at original size

Please, re-upload it in the original size (1x1 px). The site has zoom-in and zoom-out functions. Nice work btw.

I meant how the detail file is zoomed, not that the preview file is cropped.  That it would be great if the detail file were at the same scale as the preview file and then the viewer could decide where to zoom it.  So for the misunderstanding.  

the tutorial(more like course about pixel art(at udemy) gona over the process of bulding characters, and all about pixel art

that was stray pixel(probaly some miss click), i would say 90% is based on tutorial and 10% is my modifications.About the size, have to crop to be able to post, originaly was 128 x 128 art

thanks for the coment, i will continue to improve my art

Nice job!  Tutorials are a great way to build up your pixeling techniques!  What kinds of things did this tutorial go over?  It looks really good.  Is the character style yours or more based off of the tutorial?  I couldn't tell if it was a stray pixel that accidentally got left behind or if it's a little hole in his shirt, but there's a little pixel showing next to his badge.  The preview looks great!  Pixeljoint does have a zoom feature on the submission pages, so there isn't really a need to pre-zoom your work.  Many gallery patrons enjoy seeing the original and having the ability to zoom as they please.  If you prefer it at a certain zoom, though, you could just suggest it in the comments.  Then you don't have to go to extra trouble, when prepping to submit, as well.  Keep up this awesome work!  If it turns out half as good as this one, I can't wait to see your next one!
