Inspiration is what all artists wish they had in abundance!
What you need is a portfolio showing examples of your work!
Work that you can recreate proportionally.
If you are looking for still-life images I imagine you can still do a search on Renderosity for that topic.  I've shot a lot of still-life that are not posted on the web.   You can spend hours viewing members galleries.  Another suggestion is visiting a library and look for books relating to still-life either using photography or various art mediums.
