Struggling

I have been trying to tat a snowman for homework  and it looks so simple but I just can't get it.  We are supposed to creat it on our own with no pattern or anything, just from our head and from what we've learned.  I've been trying it all weekend!  I'll think I've got it and then at the end, something got messed up.  It has to be made of SCMR stitch.  I know how to make one just can't get three in a row.
Back to trying, I have 2 hours before class! 

Poor thing is only 2 part and has bumps!
