i think the face is too smooth around the eyes and the skin tone difference on the forehead is distracting...great take on the theme though author! i'll hold my vote

very well author like it

The skin tones are all over the place, and the eyes are a bit too dark in contrast, like he's wearing very heavy eyeliner.

Yes Mossy as usual he is.

The hair unfortunately was all hand drawn as there doesn't seem to be many salt and pepper Chinese men
And for MossyB this is all Obama's skin, check his photo in hi res, he has a rather bad complexion

Sorry author, but no. You've made some color adjustments to Obama's skin, resulting in a weird pinkish patch on the side of his nose and his cheek, and have lost some of the cyan tones on the face, while keeping them on his ears..."Bad complexion" is one thing, inconsistent coloring is another.

As for the hand drawn hair, it looks it. There is no skin visible at all beneath the eyebrows - Even the thickest hair shows small bits of the face along the edges - and the color of the hair on the head (as well as the eyebrows) shows far too little gray to correspond with the basically white beard...

Good attempt author, the idea is great but the blending needs a little more work!
Best of luck!

Where does the hairline come from? Seems like a SBS is needed here...

Great entry, I think the blending is fine....and I believe the hair is drawn (drawn well too) only nitpick would be that I would have prefered the hair to be more grey. Best of luck author & well done
