I hope you don't mind some hyper-detailed constructive criticism :) I don't know how to use Blender, but I'm good with faces and watched a loooot of Supernatural back in the day.
- while the bridge of Jensen's nose is pretty narrow, his lower nostrils are quite a bit wider than that, and the tip of his nose is a little more upturned.
- his nose is also more angular. I'd take a look at multiple pictures of him with various different kinds of lighting to see it more easily, but here's a good one:
-cheekbones are also more angular and (I think?) protrude slightly more in front. hard to explain. I think this pic shows it more clearly though
- cheekbones are also too wide
- lips are slightly too wide, too, and the upper vermilion border is more rounded/doesn't "swoop down" like that, so to speak. you got the pout down, though. lol
- his face shorter than that; there's too much space between the bottom of his nose/lips and lips/chin.
- I also want to say that his chin is slightly wider than that.
hope at least one of these things helps!
