Well, as I mentioned in an earlier post, I want to really do some studies on Eagles, so I've been sketching them and making observations about their proportions and such. Here are the first of my sketches. I will probably sketch something else in the empty corner of the paper.
Here is my sketch book page with notes about my observations, I think the eagle at the top right looks better, and I think my notes about the eye and beak explain why, however, the heads are at slightly different angles and that could also be the main reason. Or maybe the one on the right is just a more handsome bird. If you can't read the notes, just click on the picture, you should be able to see a larger version. If its still too small to read, this might help: Basically they are just observations about the proportions. from the end of the beak the base is about the same distance as from the base of the beak to the eye. Then from the end of the beak to the pupil, about the same as from the pupil to the back of the head at eye level. I also noted that the beak opening lines up with the front of the eye, and that I didn't do that on the sketch to the left, which is whey the eagle on the left looks like he has too big a mouth.
Below I noted that the eagle from shoulder to where his tail begins, is about the length of three head-and-neck lengths.
