Well, this might be a good LH for you to learn a few tricks on. First, I think an entire swap of the body is in order, which would teach you how to remove and replace a torso. I also know why you don't fit the hat on better, it is probably because the hair pokes through when you try. This would be a good point to learn out to chop off a part (i.e. the top of his head). The feathers is a matter of learning how to use the features of Blender. There is no real way for me to tell you what to do about it, I can tell you how to do it, but the doing would be up to you. Basically you want to use "scale on axis" and "rotate" features for that one. Again, I can't literally tell you what to do here, but you'll get the hang of using them after a while. But don't forget you have to apply scale and rotation once you get it in the correct spot (I believe it is Ctrl+A). The background is a bit more difficult, and is one of the things I hate doing. Your choice is a very good one, I get it, but the thing is with a bg like that is that you have to be careful to think about what it would be like to actually approach a man in an apple orchard.
The trees would be moving around, or at least the leaves would be rustling. So what you can do about this is go for a wider shot and blur it so this isn't as apparent, not to mention that the clearly photographed BG you use contrasts with the cartoonish LH you created. The BG is part of the LH too, and in my opinion can make a decent LH great, or a great LH just decent.
@ Kochman; my quote wasn't mean to mean anything other than what it says, I make no secret of the fact that I am an atheist, but I am not an aggressive one. I respect peoples' rights to believe what they want, so long as they respect mine not to. I posted that quote because I hate hearing the "United States was founded as a Christian nation" nonsense. In fact, the very fact that George Washington said your quote (or more importantly believed in your quote) and also said mine only enhances the quote I used. Even a man that staunchly Christian readily admitted that the country he helped form wasn't based on Christianity.
