I drew the Deku Link years ago and just recently came across it again. The Poe is more recent.
Also, I know I should have colored the Poe darker, but the pencils I used didn't cooperate very well. I would love to receive constructive criticism so I can improve my skills.
I don't have a scanner, so I apologize for the image quality.
I know the Poe isn't as good as it could be. I drew it one day at like 1am so I was rushing to get it done before I went to sleep. Bad idea now that I think about it. I'm planning to draw it again so next time I'll find a picture of one of the lamps for reference.
Don't be afraid to deviate from the reference art though! Maybe it would be cooler if you made the lamp more fancy that in the concept art, or a completely different style, it'd be a great way at honing your skills and originality. Great pics though!
Deku link is too cute. :3 I like the Poe, too, although I think sometimes you should try and add a dash of Nico to the things you draw. To make them the way they're supposed to be, but also make them your own.
