Just a thought:
Mango has a very fast playstyle, and his tech skill is top notch...
If you're ever described (or think you are) robotic, perhaps it has to do more with falling into patterns, etc?
It may be an incorrect description; being fast does not necessarily nullify being smart. I mean, people described m2k as a robot for ages... he was certainly capable of adapting etc. Regardless, if you still feel that you need to work on other things, I recommend playing a different character while you train. Try playing a character that cant rely on tech skill etc to beat the opponent. Or perhaps pick a character who relies more on adapting to the opponent, etc. Any character other than fox or falco, really.
I personally thinking playing multiple characters is AMAZINGLY helpful, because each character has their own strengths and weaknesses, which you have to learn to work around when you play them. If you combine everything you learn from each character's individual strengths and weaknesses, it'll help you a lot when you use your main. You can still play fast and technical, but you'll have the added insight of knowing how to play with other characters. If you can pull that off, I think rather than feeling robotic, you'll simply seem like a technical player who can read his opponent etc. This also has the added bonus of, for example, if you learn to get around let's say falcos lasers as falcon/ganon, think about how less overwhelming they'll seem when you play fox again.
G'luck, vids would be kewl =P
