Just Saying!

Just a note about myself....I'm a beginner as far as painting in oils is concerned. I am a senior citizen and retired; so I decided it was time to jump into something new. I took a couple of painting lessons and really didn't think I could learn. My instructor could see things that I couldn't or couldn't relate to, very frustrating to say the least. Then one day  I got my paints out and started a project all on my own and I haven't stopped since. I'm pumped up and have already finished a few paintings. Each one seems to improve and I'm not putting any pressure on myself. I'm reading everything I can regarding  technique, shading and values. I have a good friend that has been guiding and mentoring me. (very grateful!) If you have any advise for me or any websites that might help, it would be greatly appreciated.
