I have to remember to use an old cheap brush for a block-in like this. I tend to scumble a lot and it is really hard on the brush.
For the recline block-in I use thin paint, or more accurately, little paint on the brush sometimes thinned and scumble it over the figure. I keep it thin because I don’t want to have to deal with the tick paint later when I put layers of other paint over. The block-in is all about establishing correct values and colors. But, don’t forget drawing, that is always a part of it throughout the process.
I also try to think about the form and how the values roll over the figure giving it it’s solid quality. I try to position the strokes so it enhances the form and makes it looks like it recedes into space. This is the hard part for me. I still have a hard time figuring out the planes and the transitions between them. For the next session I may do a charcoal drawing of this figure and see if I can create the planes, maybe map them out and use them as a guide for the painting.
