Hello good morning, answering the questions:
1- Yes, I have previously worked as an illustrator for two NFTs projects, together with samples.
2- I specialize mainly as an illustrator, so my portfolio (which is in my profile) does not focus on NFTs, but I will show them everything I have done related to them.
3- It would depend on the specifications and the amount of work, right? So far I have original works, not procedural, so I'm not sure.
4- I don't work with 3D.
5- It would depend on the complexity and the degree of details of the characters, but perhaps it could have a complete base in one, two days maximum.
