Hey im notezz, I specialise mainly in stud style builds for maps and modelling.
I make sure my builds look neat, polished and properly made so there is no issue with it.
Also, I ensure that my builds satisfy my clients and also let them see my progress to make sure they are happy with my build.
I take clients feedback and use it to make parts they werent happy with better.
My commissions usually takes 1-2 days if it is like a map, whereas models can take up to 3-6 hours maximum.
I try to keep my commissions on time, but sometimes I may not.
