Mi sarebbe piaciuto avere più tempo per disegnare i modelli. Avrei voluto avere più tempo ...ecc.ecc Avrei avuto bisogno di più tempo per....ecc ecc

this is the correct translation: Mi sarebbe piaciuto avere più tempo per dipingere le modelle". I've translated literally "to paint the models" into "per dipingere le modelle", i don't think this is what you meant. It sounds weid ! If you translate like that , it sounds like you would have like to paint the body of a female fashion model. I suppose that you meant you would have liked to have more time for fashion design (for painting clothes on a sheet). In this case, the correct tranlsation should be like that: "Mi sarebbe piaciuto avere più tempo per disegnare i modelli". "disegnare" : Is the general verb = write down something on a sheet. "dipingere" : Is used when you're representing something on paper by a brush. A painter "dipinge" whilst an engineer "disegna". I hope it has been helpful. Ciao
