OK so I can upload one more image since my 3 post, i was attempting a revision of my second one?
as I mentioned previously the script doesn't make a difference between designs or revisions. You are free to use your 3 entries as you like. You will be granted an additional entry in the case if the contest holder requests it.
in your cace, your entry #29 was noted as "needs work" which means that the Contest Holder (yes in this contest it's me

) asks you to submit a revision and that now you have a right to submit 4 entries in total.
