Disagree. Looks great.
Yes you can looks great Hoai
Yes you can
I like the colors
I'd say that you really can draw sci-fi
Like how you went for cubic shapes on the suit. Maybe you didnt reach the sci fi aspect you wanted because the texture was too similar to cloth ? Idk. Maybe you could go for a more mech like suit, if you want it to be more sci-fi looking ?
It's hard to say exactly what it is. It's partially design, it's partially texture. I'm not unhappy with it but it's not quite there. Doesn't mean it wasn't fun in the meantime though!
