Greetings, Sir/Mam
I'm Chris, I'm mostly an analog drawer, my style is manga oriented (typical shounen), as far as to pretty characters, I am adapting to the style of Takeshi Obata (Death Note, Hikaru no Go) and Yusuke Murata (Eyeshield 21, One Punch Man)
I have used to draw manga as back in the college day, I'm producing an indie manga (posted into local magazines), therefore I do understand the human anatomy, materials shading and the lightings.
For 4 illustration that you have shown, I am capable to deliver it in 5 days.
I hope to hear some good news from you, Sir/Mam.
Best regards! :)
