You know, I am impatient with my coloring and drawings. That is something I am working on because taking your time on the comics is very important because you pay more attention to details.
My line art imo looks better than my coloring.
Try to have an end goal in mind, that pushed me to do a quota of finishing at least 10 pages in a month. Like others said take breaks too so you don't burn out.
My art isn't so great but I am trying my best and get better.
Have a good day,
