That looks about right you need the meat of your finger to control the strings. Although your fingertips looks wet and shiny, it should be the opposite, lol. I couldn’t keep my fingers from being too dry playing. Sometimes I had to wear glove it gets pretty bad, but wearing gloves makes everything too slippery.
It would not be as thick and hard as the guitar’s fingertips but it would get sandier and rougher if it’s too thick then you are pressing the strings too hard.
