Jeanne, that is the beauty of doing these, is that it is all about what makes you happy that counts. Also the scenes can always be rearranged at any time to depict whatever creative mood you have for the day. If you filled it all the way to the top with soil you will probably need to take out some soil when you add your plants unless starting with smaller plants with small bare roots. For your light weight dinos it helps if you glue there little feet to stones with some weight or you end up constantly picking them back up from wind, critters, and rain. I found that to be the case with some four inch cutting pots I played around with. It took some of the joy of my little scenes away always having to fix them every time I watered. After I glued them to a rock they now stay in place and I am much happier with them.
