Small oil sketch

Got myself a pre-made cigar box today from Michaels and added some scrap wood to make a little portable paint box. Of course, I had to break it in so I did a 5.5 x 7 inch oil sketch from an image ref from the internet. I didn't use any white on this .. the colors I used were lemon yellow, yellow ochre, burnt sienna and ultramarine blue. Not too thrilled with the results ... too much yellow
