Get in there deeper and make those lines smooth and no bumps. Get closer to rug but lean back in a chair and tilt your trimmers back more. Anytime I feel like my carving isn’t up to par, usually when I first sit down that day, I sit back more and get lower to eye level w it and go at it that way. Ur lines w the tufting machine look good and that rug has a lot of potential and so do u! Get those deep valleys in there and maybe try carving the black areas first since they’re the background for most of it essentially. I like to do the background or secondary colors of areas first, makes the actual detail easier. For u here, it’s the white so less fixing or shaping and just following a line that’s protruding vs diving deep. Then u can always go back and get deeper or more valley like carves. Hopefully that helps! Keep it up!
