If you want to increase feedback and comments, visit other people's hub and comment on them - they may check out your hubs and comment. But chances are, they will all be polite and nice. See above for a critique.
If you want to increase traffic, you need people from outside HubPages. Create links for yourself from other sources. You can research how to do this by reading helpful hubs on the subject. In the search bar beside the word 'hubs' on the top of the page, write 'how to increase traffic.' You'll find lots of tips. Also, it takes time and patience. Good luck!
