Calvary

This was my first attempt at piecing together scans and it did not go very well. It was a total of six scans (which you can probably pick out in full view). The bottom scans were at a totally different contrast level than the top. Also, I do not understand how it could possibly not line up.

There are quite a few areas I am unhappy with. Not sure adding the trunk of the tree in the background was a good move. The guys head looks too small to me. The actual size should be about right, but it looks goofy. I had to make up the eyes because he was wearing glasses that were not really period. The mane bothers me. I usually do hair shapes and then add individual lines at areas of contrast. I tried doing individual lines.

Any opinions or advice would be appreciated.
