Perspectives and drawings get better with time and practice. Just keep on practicing and you'll improve.

Oh and I can relate to the sleep thing. I'm usually up till 1 in the morning, drawing, because I can't sleep! Ugh, I get around 5 hours sleep on a good day... T_TU

Confusion is the spice of life... I think?

Wah!! Only 5hours??? That is not enough even for adult..!
Better force yourselves to slp early if not you will get weak easily ><
Plus a healthy body aids in producing nicer work.. believe me man ><

Yup! And I'll force myself to practise more ^^
Cause I just got a bad critic from my teacher today.. saying that my manga's character drawing fails T^T
Wah!! I got a bad shock then after that, the shock turns to sorrow D':
I really need to practise practise practise... Sigh...

Aww, don't feel bad about critiques, even if they're bad you can learn from them and improve. My art teacher really dislikes any art with a "manga or anime theme", so I had to tone done my style for a bit, but now he's okay with it, probably since I improved my proportions etc. I think dislike of manga is just a general art teacher thing.

Yeah I'm 16 and I get, what, 3-4 hours less sleep than I should? =_=U
Oh well, I actually function just as well on 5 hours sleep as I would on 10 or 12 hours sleep.
I can't force my self to sleep early, I can only sleep once I'm actually tired... Oh well, it's not the worst thing in the world! ^-^U

Lol! Sometimes even if I'm sleepy.. I would still continue surfing the net till like 3-4am (reading manga online recently).. Then wakes up at 11 in the morning 0.0
I'm actually more energetic at night.. Plus my idea too >< But this whole routine seems to make me more tired in the morning... :c
