Can you help me comparing Da Vinci and Picasso?

Wow, That's kinda deep. Before Picasso entered his cubist phase, he did some impressionistic portraits (see his blue period) that seem vaugely reminscent of da vinci. But Da Vinci was an early Renaissance artist and his paintings were very literal. His sketches revealed a keen eye for observation and detail. I think both artists had an eye for detail and both were very influential to their contemporaries as well as later artists. But Picasso's abstractions really set him apart from the Rennaissance and DaVinci did a lot of mechanical drawings (see the aerial screw schematic, and other plans for machines). Also Davinci did a few sculptures of bronze. I may be wrong, but I think Picasso only did drawings and paintings. Plus Picasso made way more money.
