Great stuff so far. I love the atmosphere and mood in the first piece as well as the one where it's raining... and that painting is coming along nicely.
keep up the good work
great to see you working with so much dedication!!
I would recommend to use raw umber with something like this - red umber is a really saturated (high chroma) color, you might have to fight all that red in later stages. Raw umber is more quiet and better suited for copying a painting like this.
If the image you are copying had a lot of saturated reds and oranges, burnt umber would be a good choice.
(sidenote: umbers in general are good for underpaintings because they dry faster than most other pigments)
- post an image with your painting next to the rembrandt, at the same size!
- you obliterated all the interesting background texture with a flat tone now : ( you'll have to go back in and put texture in with several layers, to get the effect rembrandt got
- proportions are decent but not great - check the eyes especially, can't leave them like this..
buon lavoro comunque!! KEEP GOING!!
