hi there,
No one has 300+ in a few minutes - everytime you relist, the views do not reset. so dont worry about that :)
i think that your pictures need a little editting. try using an online editor. i really like picnik.com (i use color adjuster, wayyy up the exposure, and the sharpness just a little). but brighter/lighter/clearer pictures pop and make people click on them.
also think about the time of day that you relist. for my stuff, lunchtime (11-1 est) seems to generate the most views.
you're keywords could be better. check out what's trending in the treasuries. right now words like "springtime" "mothers day" and "pastel" are trending topics, so those would be good to include (if they are relevant).
i like how elements of nature inspire what you make. you start off your description with one little line about it that intrigues me, but it might be nice to elaborate on the story of how and why you made it.
i hope this helps!
