I have found larger scale aircraft harder to profile. Markings on this 43rd BG bird taken from the crash site, excavated a few years ago. I have found that, no matter what i fiddle with, its all a compromise. I vote the Liberator the hardest WW2 bomber to profile, mainly because of the sliding bomb-bay doors, and all the fiddly bits. Any ideas for improvement?
Looks good to me For a profile of a large airplane, it can be hard to bring out all the detail in a small area as you have displayed. To me, I would tone down the windows some as they tend to stick out too much versus the rest of the airplane. That's the only thing I see so far! Good luck!
So if I may
1/ the window is not flat so shadows are completely wrong
2/ too intensive shadowing on the interior
3/ no shadow at all? at least on the lower part there should be some darkening...
4/ the lines look like hand drawn...i do not like em
5/ the shadow of the engine on the fuselage is missing...it should be there, as the angle of your reflections shows that it is not direct 12oclock sun...
6/ red fire extinguisteh plate is missing here I guess. or show photos that it wasnt mounted
7/ again the bulb on the glass was not so bulby that it should have such a reflections...
nice profile..I am battling with B-24 a lot...cos my PC is not able to work with it Zamex made me 1:19 or 1:9 lines...so MONSTER
And finally, reconsider the glass colour...it is too darkvioletosmething..I do not like it...
This is a copy and paste from another posting but the rules apply here.
What I do when stating a profile now, is to brake it down into it's parts because there is just too much to take in too much going on, you'll only end up missing things out and in the end this will effect upon your profile.
1/ The Line Drawing
2/ The Painting flat 1D image i.e. (Spinner, Fuselage Upper/Lower, Wings)
3/ The Texture (Canvas, Metal, Wood)
4/ The Highlights and Shine.
5/ The Shadows and Shading.
6/ The Ware and Tear (Oil Staines, Paint Ware/Chips, Smoke)
If you work on something like this alternately you should soon see it coming to life, but like Jester said always look at photos of the real thing. Look at one of the above and transfer it onto the real A/C to see how it looks in the flesh.
