Base of bulb should be wide enough to fill the whole neck area...

The blending could be better indeed, but it made me laugh though . Cool name for this work author.

Yep, it's quite funny! Yes, he can... what? Light?

yeah, ill decrease the size of the original obama..
And duke, how do you think i can increase my blending? Any suggestions?

I'm with CMYK46 on that, make the bulb base to fit, and then start applying shadows on one layer and highlights on another. Lighting is ok, but the bulb base seems a bit light to me compared to the surroundings.

i think, Duke, when taking a photo of this kind of celebrities , there are a lot of light sources included .. Maybe a BIT too much lighting, but i think that's ok . :p

good job

A much better fit now

They offcourse need a Lighted One now

Thanks for all comments! I don't know if there is anything more i can do ?
