Prize Game

It seems that small details of my Creations differ on each platform. Can you find them? Let me know through the comments.
Among all the correct answers, I will raffle a hand-signed Creation as prize and, depending on the donations collected on Tipeee and buymeacoffee, an as yet undetermined number of small Creation-prizes.

Event period: April 25th, 2021 till December 31, 2021
Platforms: | | Redbubble | tipeee | buymeacoffee |

The winner(s) will be chosen at random amongst all right answers and be announced on this page under their username on February 1st, 2022 and, if possible, informed by site mail and an answer to their comment.

Prize Game Rules

1. In this Prize Game, a hand-signed Creation prize and an as yet undetermined number of small Creation prizes will be raffled off among all participants.
2. You can use the comment function on the individual platforms to participate. Registration with the respective provider is required for this. The competition is organized exclusively by Bolzef himself. The respective platforms do not participate.
If another platform is added, all previous answers are still considered correct.
3. Minors or those otherwise restricted in their legal capacity may require the consent of their legal representatives, unless their participation is generally prohibited.
4. Multiple comments under the same post will be deleted. It is not possible for Bolzef to check whether a person creates several user accounts on the platforms and thus participates more than once. However, in case of a win, Bolzef reserves the right to hand over a maximum of 1 prize to one person.
In case of violations of the rules of the prize game or the use of technical means or other manipulative aids, Bolzef is entitled to exclude participants without giving reasons, to withdraw their winnings or, if necessary, to demand them back.

6. After the competition has ended, the winners will be notified on February 1st, 2022 by reply to their comment, site-mail and Announcement of their username on this page. If there is no response from the winner within 4 weeks, the claim to the prize expires without replacement.
7. Bolzef will notify the winners of the prize and ask them to send their contact details so that the prize can be sent to them. Bolzef is entitled to transmit the relevant data required for sending to a shipping company.
8. Bolzef assumes maximum shipping and transport costs of up to 30€. Any additional costs are to be borne by the winner. Bolzef is released from all obligations with the delivery of the prize.
9. If, for reasons for which the winner is responsible, the prize cannot be delivered within two months after the notification of the prize, the prize will also be forfeited without replacement.
10. The law of the Federal Republic of Germany applies exclusively to the implementation of the Prize Game by Bolzef. In case of any law questions the German Version of this rules will be the valid version.
