Oh my god, I remember buying these! I wish I would've bought more though cuz I only got five.(it's not enoughhh!!!! TT^TT)
Anywho, I love the artwork for these, you capture the characters really well in your style. One of the things I think I love the most, besides the drawings themselves, is the textures and colors of the backgrounds. They compliment the pallet and designs for the characters amazingly! Great work!
