My first riveting experience

Being totally new to silversmithing, have always thought that soldering was the easiest method for connecting two pieces. Today I thought I will try riveting and the first attempt was a disaster. Basically I wanted to connect two pieces of flower. I almost gave up and thought will do soldering in the middle. Then I thought sometime in my silversmithing career I need to do this, so why not now? Tried again and succeeded. I actually want to block the bottom one too, but the stem looked nice so just soldered from behind. But with the top rivet itself the pieces were secure. Believe me, I checked.

I know that the piece is not very neat. But I was so impatient to try the rivet, that I just went on did that.
