Although a hobbyist, I believe that you are an above average landscape photographer. You are right – not so good with people.
Going through your photo gallery, I think that you have a good sense of composition and lighting.
Don’t ask for people to look for flaws as they will definitely find something even if there is nothing there. Ask for a critique (good or bad). This way you can keep doing what you are doing right and drop what you are doing wrong. Personally I think the right are much more than the wrong.
