I'm using SAI atm but i want to try something else ;v; I draw on pc

i want to make the colors on my art look better but everytime i do a drawing it looks really blurry, i tried adjusting saturation and that did help but they still seem so blurry and everytime i look it up the advice I get is all over the place, i look at other peoples art and it doesnt look even remotely blurry while mine literally always do lmao
