Al-jawab billahi at-taufeeq (the answer with Allah's guidance)
It is Haraam to draw animated pictures like cartoon characters etc, and the income earned from it will also be Haraam.
Narrated Said bin Abu Al-Hasan
While I was with Ibn 'Abbas a man came and said, "O father of 'Abbas! My sustenance is from my manual profession and I make these pictures." Ibn 'Abbas said, "I will tell you only what I heard from Allah's Apostle . I heard him saying, 'Whoever makes a picture will be punished by Allah till he puts life in it, and he will never be able to put life in it.' " Hearing this, that man heaved a sigh and his face turned pale. Ibn 'Abbas said to him, "What a pity! If you insist on making pictures I advise you to make pictures of trees and any other unanimated objects." (Bukhari 3:428)
And Imam Tirmidhi relates that the Prophet (Allah bless him and give him peace) said, “On the Day of Judgment, part of the hell fire will come forth with two eyes with which to see, two ears with which to hear, and a tongue with which to speak, saying, ‘I have been ordered to deal with three: he who holds there is another god besides Allah, with every arrogant tyrant, and with makers of pictures.”
And Bukhari, Tirmidhi, and Imam Nasa’i relate the prophetic hadith form Ibn Abbas, “Whoever makes a picture, Allah shall torture him with it on the Day of Judgment until he can breathe life into it, and he will never be able to.”
