My 3D modeling Adventures

I've been trying my hand at more 3D modeling in a long attempt at improving my skills. I figured I would make a thread to show what I've made and get some much needed advice and criticism. Suggestions are welcome. Thanks!

Things I made so far:

Made a Federal Signal Sentry rotator so Izick could watch some 3d modeling in zmod. The reflector doesn't belong to me, but it's temporary until I can make my own. As it sits, it's about only 700 polygons.

Made some updates to the Whelen Raider. It now has 3d ridges (that don't add too many polys), labels by NeOnLaZeR ,and a few different variants for an up coming project.

Nice. Never saw those mounts before.

Thanks. I assume you're talking about the dual module? It's some proprietary dash mount, and I couldn't find many reference pictures, so some of it was guess work.

I haven't updated this thread in a few months, but in that time I started learning 3ds max and here's what I have to show so far.

Rockwell Collins iForce (knobs by five0, HCD edits and some textures by desmond, main textures by neonlazer)

Vigilant Video LPR

Edit: I know the keyboard texture is green, and has been fixed since those pictures were taken.

I have to ask, since this looks very detailed: What's the poly count?

Have you considered using normal maps for the keyboard? The touchpad could use some depth, for example.

The entire iForce setup is 4991 polygons, and the Vigilant Video LPR system is 8109 which is pretty high because of the detailed mounts and wires.

I didn't really see a need for normal maps, since the key caps on the keyboard have a printed legend, and I made the track pad 3d, although it could use some edits to give it more depth now that you mention it.

I figure it's probably time to show this, as it has been sitting in a folder untouched for several months due to my mediocre photoshop skills and knowledge. I present to you today a Soundoff Signal nForce lightbar. The poly count is ~13k.

Thanks to Desmond, Neon, and Patrol31 for help and info.
