Expensive equipment does not create skill. What actually changes your working speed.
A good tablet feels like it will make you draw, but finishing something comes first. Drawing one short episode end to end on whatever you already own reveals concretely what is uncomfortable. Buying equipment that solves that specific discomfort is far more accurate. For some the bottleneck is screen size, for others pressure sensitivity, for others the software.
Input devices split broadly into drawing directly on a screen, and drawing on a tablet while watching a separate display. The latter takes adjustment but costs much less. Screen size affects working speed directly, and pressure levels affect line expression.
Webtoons run as one long vertical strip, and making a single file endlessly long overwhelms the software. The usual approach is working in fixed lengths and joining them at the end. Resolution should match screen viewing; setting it as high as print only makes files heavy. Platforms publish recommended specifications, and following those is safest.
Colours that looked right on your screen appear different on someone else's. Dark scenes especially, clear on a bright display, turn to mud on an ordinary one. Checking on a phone periodically while working helps. It is worth checking that text has enough contrast against the background too.
Corrupted working files and failed devices costing people their pages are not rare. Saving to a location that backs up automatically, and keeping a separate copy of finished episodes, is a necessary habit. There is no recovering from this right before a deadline.
