Hi Samantha! First of all, I am sure you will make it work, because your work in general is just amazing! If it might help, I think you should let the fondant dry just a little bit on the cake before doing the R I work. When the fondant has had time to harden just a tiny bit, I think you will have less chance of bleeding. If I make a tiny oopsie with the piping, I normally take a damp(not wet) paint brush and very carefully with as few strokes as possible remove my mistake. Hope this helps and all the best to you!
