Thanks for the tips, Peter. I was pleased with the fact that I remained quite free with the brush strokes and the way I went about it. I liked the effect I could get by 'letting go'. It was the result I was going for, and definitely a look that I'd like to maintain. I'll try a photographic one too, just as a test. I'm not very pleased with the final result, I think it looks a bit muddy and grimy and lacks life.
I agree with your points, I should be a little more precise with the important features. In this painting I felt the shadows were maybe too dark, and her right eye (the one in darkness) is not very well painted. I also think a different background might be beneficial.
With regards to my normal way of working, I normally feel unsatisfied with a piece unless it is photographic, which is why I always use pencils or pens and never paint. My girlfriend has always worked with oils so when we were in the art shop I bought a small canvas and decided to give it a go myself. I really enjoyed oil paint as a medium and definitely want to start a new one very soon. Any more tips or critique will be very welcome.
Oh and Cynthia, thanks for your reply to my apology. I'm nowhere near good enough to ever make a living from it, but I'm only just 24 (oh, that sounds old) so you never know.
Thanks again.
Adam
