you very much get what you pay for.
Point neatly illustrated.
Sorry, Ade — there's a reason there are zero professional letterers using Clip Studio for lettering. It doesn't offer anything like the fine-grained type controls needed for this sort of work, it doesn't support OpenType features like autoligatures (where typing, say, 'EE' swaps the letters out for two non-identical 'E's), it applies faux italics to text even when you have an italic version of the font installed.
In short, it's shoddy and it gives shoddy results.
Also: if you're looking at your lettering and telling yourself that it's of professional standard, you need to go back and have another look.
Why are there no crossbar 'I's on the pronoun 'I's in this sample? Why didn't you turn 'mind' on 'made up your mind' onto a new line to make a nicer shaped text block and fill the balloon space? Why isn't that balloon cropped to the top panel border?
I don't have time for a detailed critique this afternoon, and I appreciate you weren't asking for one, but if you're going to come onto a thread where someone is offering to pay a professional letterer and offer instead to do it for free, but to a much lower standard, you're going to have to anticipate a bit of pushback.
