I really like the look of these rings, but wouldn't wear one myself - the prongs standing so proud would make me nervous that I'd either maim my son, myself or my DH with them, or catch them on textiles risking opening up the tension setting and losing the stone.
If the prongs were given a more traditional treatment and hugged the stone I'd say I love 'em! Your finishing is really nice, too.
I agree totally with what you said about the setting being too high.
I think that the ring could be improved so that the prongs follow the culette and shape of the stone a lot more closely. That would lower the stone into the setting more and shorten the length of the prongs.
I did this using CZ stones that have very deep culletes, I think a gemstone such as a real topaz or citrine would have a shallower culette and make the whole thing set lower.
I have tried a couple of pieces using the Wiresmithing technique, but mostly pendants...
Your ring is lovely, very attractive...I as well wouldn't feel comfortable and secure with the prongs extending above the table of the stone....it would definitely be easier to wear if the prongs were shorter and closer to the girdle.
By the looks of your ring, you have good techniques!
The only thing is, you can hardly see the wire wrapped around the band when it is on your finger, so you might consider moving the wire higher up on the sides. and as others have said, the prongs are a bit risky.
But other than that, i think you have a great start of a great design.
I really like the concept and the rings are beautiful.
From a practical standpoint, it seems that they'd be a lot safer if the prongs were flush with the stones. One thing about jewelry is that we never want it catching, snagging, scratching or taking an eye out.
