I think you are on the right track here ! Well done.
But look at some photo reference, and you´ll notcie that the highlight isn´t as uniform as you might think. it´s all a matter of the angle of the surface in relation to the source of light...all surfaces with the same angle will have a equal amout of highlight. Notice the nose of the F-15 on the attached photo, the highlight is focused only underneath the cockpit, and is hardly noticable near the tip of the aircraft...This photo is taken from a 9 o´clock position (roughly) with the sources of light comming from a 9 o´clock high position. The light from the sun is reflected in the surface of the aircraft and into the lens of the camera, like a ball bouncing off a wall. If you imagine the light from the sun is reflected from all over the surface of the aircraft, only a fraction of the light that bounche off the surface will hit directly into the camera...most of it will miss, and therefore is not visible to the camera. (does this make any sence ?)
There´s also differences in how focused the a highlight is, depending on the texture of the surface (the attached file shows a cylinder with various surface roughness). A F-15 (at least the USAF versions) has a very non reflective surface, so the highlight should be broad and not very bright (again look at the photo above)
Other than the direct reflection there´s teh diffuse highglight, which i think looks pretty good on your drawing (pretty much: all surfaces pointing upward is lighter that those pointing downward). I would howevere decrease the intensenty of the diffuse highlight a great deal.
Also, you might wanna consider breaking up the highlight abit...there´s slight differences in the properties of even the smoothest surface (on a aircraft at least). so try and do some lighter areas and some darker spots, here and there

Thank you for a polite explanation.
When I referred to the photograph, it was understood for the first time that there was light that in to the lens only on part.
A lot of photographs of F-15J have been taken in Japan. The stereoscopic effect is lacked because the light is weak.
I became reference very much.
Hereafter, your explanation will be used.
Thank you.

It is a process. The outline was lost. It devises it the panel line. I added a little dirty expression and corrected the highligh

I think you are getting much closer ! Good job !
Still i think you can work on the highlight. The highlight is very uniform try and break it up and still i would say that it need to be more intense.
One trick to see if you got it right i by removing the bottom layer and leave yoru shades and highlights on a medium grey background. If the shape of the aircraft is clearly defined, then you got it right !
Keep up the good work !

The F-15 has a bulbous canopy that can be rendered with appropriate shadowing and highlights. TYhis is my suggestion....

very, very nice!!Much improved over first version.
Don't forget to add the shadow under the horizontal tail.

Thank you for the explanation.Originally Posted by Aircraftprofiles
The highlight is corrected more accurately.
The correction is tried like understanding the shape of the aircraft.
Please give time to me a little more.

Ugo san,
Thank you for the explanation.
It was possible to understand well.
I will correct the shadow of the canopy.

Thank you for your comment.very, very nice!!
Don't forget to add the shadow under the horizontal tail.
I will surely put the shadow of the horizontal tail.
