Don't sell your work short JakTorlin.
For simple basic work your stuff is pretty good!
As for your particular models, I got one good comment and one CC I'd like to share.
First the comment: I really like how you did the wings on the dread, leaving just enough black in the shading to really give the multiple feathers proper depth. I've seen many people just slather on the white paint and dont even bother with shading, and it just doesnt do wings justice. Good job man.
Now the CC: With shading in mind, I think your models could use a wash on some of the lighter colors like the metals and yellows. Its a quick and easy way to give shading to a model and give it that nice 2D look. Normally how I've seen it done is you would basically paint the part in question (lets say the head in this case) the color you want (yellow). Then you would wash the said part in what ever wash you see fit (in this case I would suggest a black wash, null oil), then let it dry. Now because this is a darker wash the color will loose much of its brightness, so then after the wash has dried, just go once more over with the exact same color as before, and just hit the top edges of things, making sure not to paint over any of the nice black lines. After that you model will have a nice bright color with perfectly defined shading for depth. Making it look just SO badass in easy steps.
I really believe if you try this out, it will bring your models to life. It'll also open alot of different techniques to you as well.
