your art is awesome! you may need imrovement just keep drawing and more people will like your art.

Keep drawing and you'll be even better. Don't think your bad 'cause your not, u just need to keep practicing o(^u^)o

I'm more of a casual doodler, so I'm afraid I'm unfit to give actual critiques pertaining to your gallery ,
but the way I see it is...

If you enjoy drawing, just keep going at it! You'll only continue to improve naturally with time. c:

-Now, if you truly want to make huge strides in less time or aiming for a career in graphic design..
there's MUCH you need to study
(anatomy, lighting, textures & perspective/for example)
If your family can afford it, sign up for a few courses
A good teacher should be able to point out your strengths & weaknesses to better guide you.

Luckily there are plenty of wonderful guides online
(DA is full of quality tutorials & studying Colors replays can also prove valuable)
yeah.. it's a cr4p ton of work, but if you're determined..

*Most importantly*
Do it for the passion[!]
Don't sweat the # of followers on a silly app.
First focus on finding & refining your style.

Imo, drawing for your own amusement is far more important

Whether or not you choose to share your work with others is up to you.
But please.. don't quit on art if it makes you happy
