ATENTION!
1 - I'll only hold up to 2 months of backed up sketches. You can only have up to 6 sketches at a time. So if you subscrive for 6 months but don't ask for the sketches you can only ask for 3 months of sketches(Including current month), the rules also apply for completed drawings.
2 - The finished pic is only aplicable if you are subscribed non stop, you cannot subscribe one month and cancel it then 2 months later subscribe again and ask for the completion for one of the sketches.
