Several years ago, I painted a picture of lilacs in a vase. I thought about using my painting as a reference, but decided to just find a photo that was similar. We are going to SIMPLIFY this a lot.
This is kind of a non-drawing, as you can see. You can draw the whole thing out if you wish, but I think it would be easier to just draw the part of the vase that you can see, the line for the table top, and a few little marks where you want the flowers to end up. I don't know if you can see these marks.
This is a close-up of how to do the flowers. I used Permanent Magenta, but any purple, pink/purple or blue/purple will do. Just dab the paint like we did for the pointillism lessons. I used my larger round brush, not sure what the number is.
Here is how your first washes of the flowers should look. You should have a few white spaces showing in each bunch. Notice that I just left some big white spaces for the white lilacs.
I started on the greens. I put a pale wash of Sap Green on the vase. I drew in and painted the leaves. I put spots of green in between the "dots and spotches" of the flowers - not too many. I put some quick curvy lines in the vase for the design.
I put a little light blue splotches in the white flowers, and put some darker splotches in the shadow sides of the pink/purple ones, darker for the ones on the left, and lighter on for the ones on the right. I darkened some of the leaves, attempted to suggest the stems showing through the vase, and painted the table a light blue, with a bit darker for the shadow on the right.
This was a quick painting.
Here is one that I did several years ago, that I spent a lot more time on.
