to give the op the honest truth, no, it doesn’t really look like Harrison Ford, so if that is your goal, you will need to spend alot more time on the face , mainly on his eyes.
but then the overall product wise, it is actually pretty well executed. The modeling, texturing and lighting works quite well, it’s just that he doesn’t look like the Harrison Ford version of Indy…
be careful with your reference, your reference seems to be a painting of Indy, which in a way already lose some of his real life characteristics, so I hope you are not using that picture as your reference for your model…
some suggestion that may help:
try to lower his eye brows so they are closer to his eyes than now. Harrison Ford has a sharper look than your model.
his eye direction seems to be losing focus, try to adjust it a bit.
other than those, I think it’s ideal to roloscope your character’s head on top of Ford’s real life picture and line up the eye shape and brow lines.
