Great idea and a nice image but I think this would be better on a different background to make it stand out more Maybe a Dark Brown Just a thought anyway the blue is a bit dull
A nice idea - very NG. I winder at your choice of blue background. It is so pale that the stone doesn't stand out too well. The light is a bit glaring on the top - perhaps lights from the sides at a low angle would catch more details of this fine point.
I love the texture you have managed to bring out. This could so easily have been "just a lump of stone".
I have 2 points
1: Background colour. Blue detracts from the tool, a very neutral grey may have been even better.
2 The hard shadow, at the bottom of the tool. Maybe a very very soft diffuse light may have softened the shadow. I think it is right to have the shadow, as it gives the tool its shape but the edge is just that tad too hard.
Cool idea, but in my opinion, it feels a little dull and void of excitement. Kind of looks like a picture of evidence shot by a detective or something. Just trying to express the emotion or feeling I get from it. Good luck!
I played around with an arrowhead too - couldn't get mine to work but yours does. Something about the blue background takes away from the image. Perhaps a more natural locations?
