Making a mini terrarium

I know you are coming here just to see this. Right?
Well, Pappa Starbucks' Mom and Sister came over yesterday.
So I made a terrarium for his sister who is still just a kid. I wanted it to be fun and cheerful and a bit fantastic- like a mini fairyland in a jar. I've been saving glass jars and reusing them a lot lately (because suddenly I'm realizing all the things I need glass jars for!- buttons, q-tips and band-aids, embroidery thread, miniature toys that I keep for things like terrariums,needles,dried herbs, spices, ginger syrup for making ginger ale, candied orange peels that I made so I wasn't wasting the peels...and because they're deeeeelicious- etc)
I'm looking at my photos of this terrarium and a little disappointed. I've been "copping out" a lot lately and using my iphone camera for things I should just use the regular camera for. And I didn't take any pictures showing the side of the jar either and how full it is.
So Little Berry and I went on a walk taking this little jam jar that I had with us. We found a patch of moss and proceeded to find a piece about the size of the base of the jar. We also had a spoon with us and scraped up enough dirt to fill the jar about three inches. We gathered a few tiny grasses and acorns and took this all home.
At home I mixed in some richer dirt from a flower pot that was also much looser. And then we tamped the dirt down for the moss because moss likes firm surfaces. We placed the grass, acorns, and tiny bird next. There's about an inch from the top of the jar left.

Next I placed the polymer clay mushrooms. I got three packages of polymer clay at the check out at AC Moore or Hobby Lobby and made these mushrooms. It baked under five minutes and I chose to leave them unpainted. I would have left holes in the stems for pins if I had thought about it but they're fine without them and haven't fallen over at all.

I will definitely be making more of these. I think they would be really nice for college students or as gifts for young people getting their first apartment. Low maintenance (needs lots of indirect sunlight and occasional watering) and lovely to look at. Also is rather dreamy and I know a certain young girl I want to make one for still.

--> on another note, I am looking for a seamless way to round the corners on my photos. I've tried photoshop (I only have 5.0) and can't get it to do what I want, and I haven't found any good online generators. Any tips besides buying a new computer?
