Don't be so hard on yourself. You're trying an experiment with a time restraint when everyone here is telling everyone else to slow down. This looks like a lemon with the stem and leaves attached and it has great colors, shadows and the values are pretty darn good too. The table/board is a nice tone and gives the lemon some vibrancy and the leaves are toned down well enough to offset the vibrancy with subtlety so I think you should call this a successful experiment.
You mentioned keeping your finished painting in the KITCHEN to dry, @alsart; I highly recommend that you find a better place as normal cooking produces all the bad things you don't want on your canvases and especially on your finished or WIP paintings including steam, warm moisture, residues from cooking with oil or fat and even the errant solid particles of flour, baking powder and others even soap bubbles from washing dishes can get on there and cause problems.
@Flatty, You are propelling right along with this. I noticed your drawing of the float doesn't have an elliptical line at the bottom of the top part. Is this because of your perspective view from your painting chair?
