I like it so far.
If you practice a lot I think you could eventually sing some pretty good songs. It's in tune all the time. There are parts that might sound better one octave higher but I am unsure if it's necessarily a good idea to push one's voice that hard especially at first. Also you're quite good at piano
It must be pretty hard to not mess up too much when playing and signing an entire song in one sitting (as in, not signing 8 second chunks at a time then mashing them up in audacity)
Is it much harder to sign and play at once than only do one at a time? In a lot of bands, the signer doesn't play any instruments.
