Chimara's Claws Final

Made in Blender. I followed Jonathan Williamson's tutorial of "Modeling a Human Hand" to create a basic starter point (the dark wireframe in the render view). After that I duplicated and separated the finger tips, and created the claws by extruding the front face and adding in more edge loops. Getting the sharp edge along the thumb claw was rather simple by adding additional edge loops and increasing the crease weight, getting the sharp point one the others was harder for me and I'm sure that there is a better way to do it then how I did it. The claws appear a bit longer then I thought they would, so they will toned down. I would like to add more curvature to them as well before I try to sculpt any detail into them. I'd really like to hear any tips you guys have or any adjustments I could make so they could look more... animalistic.
