Sketch models killing me

Been spending the whole day at home doing the 3 sketch models for tomorrow.

I woke up on at about 11.30am.

After taking lunch it was already 12pm!

used up my time all the way until 4pm to finish up my first one.

Then from 8pm until 10.30pm I finished my 2nd one.

Now the problem started.

I'm stuck with no ideas for my 3rd one.

What should I do?

Just simply crap one for Rosidah?

Should I?

Save me!
