Hey Juan, nice caricature! Good likeness and exaggeration. I also like the pose. A little flaw for me is the cigar. It is just in line with the mouth shape and also the color ist nearly the same as the lip color. So it is hard to recognize as a cigar. On first glance it looks like he has got a hole in the lip. I think you could mouth the cigar and let it stick out of the headshape on his left side. But this is already high level critique.

Hey! Nice piece! The rendering on the later versions of this smoothens out most of the hard edges and leaves this airbrush like look. Try to be more bold. Make the lighting more pronounced. The sketch is better at being bold and loose. Again, great job!
