Value -> Put your image in black and white and see if the values read properly and your focal points have the correct contrast and aren't competing with unimportant areas.
Color -> Adjust the hue and saturation of the entire image and play around to see if you find better versions of your image. Do it for long enough that you forget what you image actually looks like. Then cancel it and look at the actual color with your now refreshed eyes and see if you can do anything to make the color harmony or accents better.
Drawing Accuracy -> If you used a reference then overlay your drawing and the ref to see the changes you made when copying the ref and use warp to adjust if you don't like your changes. Or flip the canvas and check if it still looks ok or if there is wonkiness you didn't catch.
Composition -> ideally you would decided on this VERY EARLY. Use separate layers and mess around with letters of the alphabet but change them and zoom in and rotate or warp them so they aren't obviously letters anymore. Add perspective to them to test. (eg: make an S into a winding path going off into the distance, getting smaller). Play around with at least 3 layers of these and move them around until you get a good composition you like. Make one of them dark, one of them light and one of them a mid tone. Do a ton of these and narrow down to your favorite before even starting anything else. Always have a little idea or story in your head for the painting/drawing when doing these.
Gesture-> Test gesture with the simplest scribbly line drawing you can, do not advance until you have a gesture you like, do lots for each figure in your painting.
Form -> Draw through your figures and objects so you are sure of the perspective and wrapping lines and have allowed a sufficient 3d space for each object. When adding value later, always think of the LARGEST form first and then break down the smaller forms later. Eg.paint a head as if it was an egg
