awsome work… model looks great 
To me, the blood looks sorta like dried paint… That’s the only thing I don’t like about it, everything else is good
Ye the blood does look like dried paint. I guess u need to add a bump map using the same UV co-ords and make where the red was stand out a bit.
The knife is excellent and the glare on the blade is perfect.
In addition to the blood issue mentioned by the others you might want to look into the background. From what I can see, the background looks like a plane with an applied texture and bump map. The shadow of the knife seems to be falling on a flat surface, but the texture is implying a 3D surface (the light band in the top left corner followed by a dark band and a second light band of sand as you come down towards the bottom right). This illusion of a terrain does not go well with the flat shadow, causing some visual confusion.
You might try making a real 3D terrain with some subdivision and fractal noise applied to a plane. Then apply the same texture. This way the shadow will be more irregular and the lights and darks of the terrain will match the shape of the shadow.
Excellent work. Can’t wait to see your final image.
