First I'd like to say that I'm a huge fan of the Zelda games and its characters. I really like Shiek and this chibi version of him is too cute!
The time put into this must've been immense, and I can only guess how many hours you've spent on it, considering its size. I think the choice of colors is very well done, I know from other bead artists that the color palette is rather limited and they have to improvise with the shading a lot.
The ironing looks pretty even as well, which for sure isn't easy on such a large piece!
This piece came out great and I'm looking forward to see more of this advanced bead art!
