turning a sketch into vector illustration- I am a beginner

[Anna]

I have just started learning gimp, (only have an experience of using it of few days) because i needed to make a vector illustration for a project, I am only left with 10 days for the project and i still havent drawn even 1 vector illustration where as i need to create three, i started drawing using path tool but its very time taking for the intricate design I have sketched so i was trying to convert it into vector illustration using gimp and inkscape but the youtube videos i was watching were quite old so couldnt really get it done...anybody knows any way?
the illustration is for a huge object so if i do it using gimp and inkscape would it be good enough?
