Creating a Falcon's logo

I have been trying to trying to replicate this logo for my team (not to mention in LaTeX ofcourse:-)):

enter image description here

Having said that, with respect to the original figure, the challenges that I face are three-fold:

~~1. I am not able to match the blue color between the gears and the first white circle.~~ [worked as per Phelype Oleinik suggestion]

I am not able to replicate the barrel shape in the teeth region of my figure (compared to original).

Finally, ofcourse, I used a lot of helps from other answers that are linked to this question (especially, @Gonzalo's Bézier trick). But still I am not able to get the smooth finishing of my Falcon.

All helps and suggestions are appreciated. Nevertheless, any optimisations of my code is more than welcome.

I Think It's because you are using the darkercolor command. Try definecolorMyColorOneDarkHTML253F83 without the darkercolor thingy. To get the color I used gpick, but are lots of other colour pickers as well.

@MartinScharrer the teeth of a gear should be involute (be curved) see khkgears.net/new/gear_knowledge/abcs_of_gears-b/…

The original gear seems to have 10 teeth, you redraw only 9....

I was always scared by falcons. They hunt us! (With to[in=...,out=...] one can do a lot of things, and if one in and the next out differ by 180, there is no kink.)

UPDATE: Implemented Max' suggestions for the teeth of the gear and also changed the teeth of the falcon. (Those who want to object that falcons do not have teeth: here's a counter example. ;-)

Addendum: Original beak and removed things that are not used.

You could add some string around the bill so the falcon can not hunt marmots

Definitely, my falcon will hunt @marmot. Nevertheless, +1 For my tikizifying my Falcon!! I wish I could give more. Could you also suggest how to make teeth barrel shaped?

@Raaja Try newcommandgear[5] foreach i in 1,...,#1 [rotate=(i-1)*360/#1] (0:#2) arc (0:#4:#2) to[out=#4+#5,in=#4+#5-150,looseness=0.7] (#4+#5:#3) arc (#4+#5:360/#1-#5:#3) to[out=#4+#5+150,in=#4+#5,looseness=0.7] (360/#1:#2) for an approximation of the barrel shape.

For the record, the shape of gear teeth has a pretty precise mathematical definition, to ensure they grip correctly. See involute gearing on Wikipedia. The parametric representation of the involute of a circle is X (t) = r (cos t + (t − a) sin t), Y (t) = r (sin t − (t − a) cos t). Two of those curves facing each other, with a “cap,” would produce a perfect gear tooth.

I was always scared by falcons. They hunt us! (With to[in=...,out=...] one can do a lot of things, and if one in and the next out differ by 180, there is no kink.)

I was always scared by falcons. They hunt us! (With to[in=...,out=...] one can do a lot of things, and if one in and the next out differ by 180, there is no kink.)

UPDATE: Implemented Max' suggestions for the teeth of the gear and also changed the teeth of the falcon. (Those who want to object that falcons do not have teeth: here's a counter example. ;-)

Addendum: Original beak and removed things that are not used.

You could add some string around the bill so the falcon can not hunt marmots

Definitely, my falcon will hunt @marmot. Nevertheless, +1 For my tikizifying my Falcon!! I wish I could give more. Could you also suggest how to make teeth barrel shaped?

For the record, the shape of gear teeth has a pretty precise mathematical definition, to ensure they grip correctly. See involute gearing on Wikipedia. The parametric representation of the involute of a circle is X (t) = r (cos t + (t − a) sin t), Y (t) = r (sin t − (t − a) cos t). Two of those curves facing each other, with a “cap,” would produce a perfect gear tooth.
