Yep, these are pretty awesome designs. I don't think any of these showed up in the weapons drawing you made. It doesn't seem like there would be any point. You do so wonderfully with colors. I don't seem to recognize these. It must just be a long time since I've played the games.
My favorite is probably the turtle shell one. It reminds me of Mario. They're all awesome. You even show some nice background. It's just all so wonderfully flashy.
