So I have just finished my very first painting using the DMP method, a home made still life A3 size. I did not have a color checker at hand yet, and I made my color groups by eye on the palette. I realize now how far off i am from the original colors. I was working from a photo (from my laptop screen) since day light exposure changes a lot in my appartement. I have now built a colorchecker and will definitely colorcheck more.
My self-critique of things that I think I know how to work it out would be (i) value/color problems to be solved with the colorchecker and (ii) the perspective drawing problem of the jar lid.
Things I don't know how to fix:
1) dark brushstrokes on my white paper. The white is always lightening up my darks, especially at the end of the strokes (see bottom). I tried after this painting to stain my "canvas textured paper" (gesso + burnt amber acrylic), but the paper got all bended upon gesso drying. I guess this staining technique is solely for stretched canvas. I prefer to start on paper rather tan canvas for price and storage, as my first paintings won't be worth hanging... The problem might be due to my student grade paint (cobra), would that not occur with artist grade paint?
2) The background fabric looks really bad. I was unable to get a decent background and I ended up playing so much with it that it got all blended and muddy. I tried first to keep the abstractness into it as mark does with random brushstrokes here and there, but that did not work out at all. How would you have done it differently?
3) Drawing straight slim lines for the lamp, but I just saw the post on using a rigger brush. will try it.
4)The bulb area and the light passing through the silver cup holes gave me a real struggle, I gave up.
Lot of work ahead, that's great. My problems all came from steps I skipped in the method because of equipment lacking. I will try to not skip steps from here on, and maybe buy some artist grade paint as recommended all over the place in this forum.
Have a great day.
