Thanks for all the comments on the corsair/zero picture. I'm going to leave it alone for a bit (I'm sick of it right now) but I'll definitely take your critiques into consideration when I do go back and fix it up.
Rodrigo: I tried what you said about line thickness, it does seem to help (I forgot to scan the silly thing though).
Inkfish: Thanks, I'll try to put all that to good use when I get back to the picture.
Boogieman: Ahhh, now I see. Thanks!
I did a few quick sketches recently. They're not clean at all, just jotting down ideas, so they're rather messy. I'll try to do some cleaner stuff later.
A very happy hagfish and lamprey, chimera looking all creepy, me posing with my sister's sparring sword, and a robin that was kind enough to pose outside my window. I've noticed that I have a bad habit of shortening the upper arm, I'll have to watch out for that now.
More chimera body plans. He walks on two legs and all fours. Some odd wolves/coyotes/something. A few airplanes and a scribbled cyborg.
I misread the IDW for this week and thought it read "giant russian flying tank" instead of a tank that was dropped by an airplane. Anyways that sparked a whole series of crazy bombers with ramjets that would fly to their target at mach 4, slow down with moveable wings and bomb it into submission. I liked some of the designs in the middle, but I wanted something semi-realistic and those designs would have poor airflow into the ramjets.
So on the next page I stuck the ramjets in front to have access to less turbulent air and added some turbojets at the top. Ramjets can't start themselves so they need some sort of a booster to get up to speed at first. American designs usually have the turbojet inside the ramjet, but Russian stuff tends to be simpler so I stuck the turbojets on top. Makes them easier to repair. I've got to work with the wings though. I think it'll eventually be a canard setup.
It's rather odd but one way of knowing whether or not you have a good design is by how "good" the airplane looks. Unless if there are some major design requirements not related to flight, a bad looking plane will not perform well. Honest to goodness I had a whole class on this. Anyways when I'm drawing out a plane I usually pay attention only to the physics and more often than not it will come out looking decent.
