Wing practice : Traditional art 2

Well in fact I'm cheating as it technically was the first attempt - the second one is slightly seen through it if you look well. I just *slightly* failed judging my sheet's and wing's dimensions ^^
But at least that "zoomed" version allowed me to focus more on the muscles, and it doesn't look that bad. Also, the shading looks like something on that one, not like the crappy one I made in the other attempt.
But well, it doesn't matches what I did in the digital version. It just was a great and needed training about muscles.
