Hi @iqbalzr =)

You definitely have some drawing talent there ^^ ... You ask for some comments/suggestions on how to get better, and the only advice I can give is to practice, practice, practice.

So many people look at great artists and say "Oh I wish I had that talent!" but they don't realise that 90% of that "talent" came from hard work, practicing every day.

Keep on Steemin on! =)
