I think you should use a reference so it looks more like a real dagger. I don't think the base of the blade should be that thick, especially given how thin the handle/hilt is. there's banding on the right side of the blade. some more interesting reflections on the blade would also help. remember that you always have access to the WIP forum if you want feedback and critiique on your art.
Thanks a lot for the criticism, I was doing this late at night when I was half asleep. When I woke up I came on here and I realized how crappy it looked. I was kicking myself for probably two hours straight. Thansk a lot though, I'll take your suggestions in to consideration next time :)
