Getting started!
Welcome! A great knife and the shot is looking pretty good too. The materials look great. I don't think the background does it justice though.
I was just going to say (similar to Josh) that it's confusing to look at. Seems like it was rendered out with transparency and the background has no perspective, or it doesn't match the knife?
With another background, this would be really cool.
Thank you for your criticism. All accepted. What do you think, how can I improve this work? I'll do it as a lesson
