I think it is fine to use it. Splinterland's have not contacted me, and this entry sadly did not win, I think they preferred a much vibrant / cartoon line art style after seeing all the winners piece that won this week. So I thought this piece could work on your album after reading you allow multiple entries. Those cards are so sick btw, I did not know there are real live versions of them.
